Better cc linux-scsi.

Are these bugs also present in 2.6.12-rc4?

Yes, I tried a vanilla 2.6.12-rc4 and I get the same output.
I get this from 2.6.12-rc3 onwards. 

Maybe something from the following changeset of 2.6.12-rc3 ??

Gents, can you please confirm that 2.6.12-rc5 is working OK now?

Andrew,

I know this wasn't directed at me, but I can confirm that the problems I
was having with my aic7899, that James and I resolved under this thread,
are in fact gone in 2.6.12-rc5. Booted it last night. :-)

I checked 2.6.12-rc5 and 2.6.12-rc5-mm1 and SCSI comes up fine 
on both

Everything apart from the Sony DVD domain validation issue should be
solved.  I'm still trying to find a clue to the last one from the traces
(it also doesn't look aic specific ... I think the DVD would do the same
thing on a different controller).

Always a wise thing to do for SCSI failure reports.

Actually, this isn't a me too.  The previous one looks like some strange
DV failure.  This is a problem with the initial inquiry.  What's the
device at target 15?

On this controler I have :

Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: IBM      Model: DDRS-39130D      Rev: DC1B
  Type:   Direct-Access                    ANSI SCSI revision: 02
Host: scsi0 Channel: 00 Id: 15 Lun: 00
  Vendor: SEAGATE  Model: ST336706LW       Rev: 0108
  Type:   Direct-Access                    ANSI SCSI revision: 03

Should I change anything in the BIOS ?

Thank you, and please keep CC to me as I am not on this ml :-)

Well,

I just did some copy, and I didn't swap hardware ???

I think the bug report that Andrew forwarded to linux-scsi with the
above Subject: is from dino@in.ibm.com (at least, his information
matches the trace).

OK, that's roughly what I was expecting.  These processor chips tend to
be rather basic when it comes to rates and widths.

The root cause, I think, is that the aic7xxx isn't starting out at async
narrow for the first inquiry (because the original DV code I removed did
this, and I didn't add an equivalent back).  The latest aic7xxx patch
should sort this out.

So, to get all of these changes, could you start with vanilla linus
kernel 2.6.12-rc4 (or tree based on this, but not -mm which already has
some of the SCSI tree included) and then apply the SCSI patch at

http://parisc-linux.org/~jejb/scsi_diffs/scsi-misc-2.6.diff

and see if it works?

Thanks,

James

Right, but the problem I think it will fix is the initial inquiry being
sent with the wrong transport parameters.

You have a different problem, I think ... it looks like your Toshiba DVD
does somthing strange during Domain Validation ... the question I don't
have an answer to yet, is what.

Well, the attached is what I'd like you to try, capturing the
information from the initial inquiry on ... it will be quite a bit.

Hopefully it will give me a clearer idea of what's going on.

Could I just take some pictures of the boot process and send them to
you ?

Or is there any way to use an usb palm to catch the console output ?

Not really, the messages I need will be embedded in a lot of other
output and will likely scroll off the screen

> Or is there any way to use an usb palm to catch the console output ?

If it has a serial port, sure, just use a serial console.

If it doesn't, try removing the DVD during boot, then plug it back in
again and trigger a device add

echo scsi add-single-device <n> 0 1 0 > /proc/scsi/scsi

where <n> is whatever SCSI number the rest of your CD-ROM's appear on
(it was 1 in your first trace).

It should work against any recent kernel with the scsi patches.

Actually, did you capture anything more after this?

There's an indication from a previous file you sent:

Target 1 Negotiation Settings
        User: 10.000MB/s transfers (10.000MHz, offset 127)
        Goal: 10.000MB/s transfers (10.000MHz, offset 15)
        Curr: 10.000MB/s transfers (10.000MHz, offset 15)

That for some reason the bus is tied to 10MHz (i.e. fast but not ultra).
The DV began at Ultra, but it should next drop down to FAST.

Also, when it finally boots up what does

/sys/class/spi_transport/target1:0:1/min_period

contain?

Thanks,

James

No, I have waited some times, and has nothing more were written to my
palm console, I just thought it wouldn't boot further...

Under 2.6.12-rc2 I haven't this file, what the equivalent ?

Thank you very much for taking care of my problem :-)

OK, I have two things for you to try.

The first is the attached, which, I think, enforces the limits this
device is expecting.  It's really just a sanity check to see if the
problem is what I think it is (device negotiates a transfer setting it
can't actually support).

Hmm.. Should there be a pair of {}'s somewhere?

Only if it were actual code for the tree, rather than a throw away
test ... it's a single lun target, so the condition is always true.

uname -r gives me : 2.6.12-rc5 which mean it's a working fix for me !!!

Note that on the other controller the speed are quiete low ?
Do you think it's more or less safe to use this kernel so ?

Thank you very much !!!

Yes, that was just a global change to get the thing to boot.

Now try this:

echo 100 > /sys/class/spi_transport/target1:0:1/min_period
echo 1 > /sys/class/spi_transport/target1:0:1/revalidate

and look at dmesg to see if it brought the speed up (save your files
first, this may hang the box).

It don't hang my box... and I got this :

Well that's good ... it proves the theory that if the DV were correctly
limited initially, everything would work.

However ... lets see if we can get it to work properly even with the
initial mismatch.  Reverse the previous patch, apply this one and try
rebooting ...

Thanks,

James

Well, OK, three things spring to mind.

1. Try the attached patch, just in case it's a perpetual timer reset

2. You should be able to boot if you set the device speed to 10MHz in
the adaptec bios (since we should read the bios values for setting the
speed)
3. when the hang occurs, can you get an alt-sysrq-p to show the current
process on CPU?

Thanks,

I put the log of the boot : not a success.
I hope the previous repport were right : ptelnet on my palm seems to
put the log in a strange order...

I have set all device to 10 Mhz (for that controller) in the BIOS, but I
still can't boot.

MagicSysRq don't seems to work at this stage.

It's also not showing any of the debugging information in the patch, so
I think you might not be booted on the correct kernel.

Although it's doubtfull this causes it, this is a compile fully of totally
broken patches.  Please use a proper compile instead of the Gentoo
whackopatchotree.

Oops, sorry, I took my grub conf and edited the bad entry :

title 2.6.12-rc6
#kernel (hd0,2)/bzImage-2.6.12-rc6 root=/dev/sdc2 parport=auto video=vesafb:mtrr,ywrap,1024x800-16@75 vga=0xF07

to take the second option with the "console=ttyS0" and forgot to update
it to (hd0,2)/bzImage-2.6.12-rc6.

Sorry for it, I can reboot my computer at 9pm (vdr is reccording till
9pm) and then I post the result :)

And don't worry, it's a vanilla 2.6.12-rc6 with only the scsi-misc and
the last patch, I even didn't patch for latest DVB.

OK, this is what tells me there's an error in the bios reading routines
for ultra cards.

Can you try this (it should apply straight on your currently patched
2.6.12-rc6 tree)... hopefully I've been more careful in the bios reading
routines for the ultra (and fast) cards.

Thanks,

James

I was really sure I should work and I booted it without the console
switch to log on my palm, so I miss the beginning of the log, I hope
this dmesg is enough (yes, this time it booted perfectly, thank you very
much) :-)

I wonder if the speed read for my first controller with U2 and U160
drive are right ?
I'll stay under this kernel some times, in case some info are still
needed :-)

Well ... just to confirm for this one: although it's on a u160
controller, you have its speed configured in bios to 40MHz (rather than
80Mhz)?  That's what the value of flags seems to say, and we look to be
interpreting it correctly.

Yes, due to those problem, I have reduced all devices speed on both
controllers. Now I think I can put the HD to 160 and my CD-writers to
20 :-) (Maybe I could try to also put the DVD-Rom to 20).

Do you think it's safe to use this patched 2.6.12-rc6 (I could stay
under 2.6.12-rc2 till 2.6.12-rc7 or 2.6.12 comes out) ?

Thank you very much,

Actually, I think the problem is that the DVD-Rom thinks it can run at
20 but actually can't

Well ... look at it this way ... if no-one finds anything wrong with the
patches, they'll be going straight into the kernel tree after 2.6.12, so
I trust them as much as that ...

You are almost certainly right : setting the speed in BIOS back to 20
and I can't boot, but I can with 16 :-)

I will test it for a few days like right now, and I have now set all
speed back to full (except for the DVD) :

Re: What breaks aic7xxx in post 2.6.12-rc2 ?

[Frank van Maarseveen]

2.6.12-rc6 seems to hang in the aic7xxx driver here, pausing a few seconds
dumping state, pausing a few seconds dumping state again. I started
to take pictures of the screen but suddenly it got out of the loop and
here's the log. I'll try the patch to see if it fixes anything. First
some output of /proc:

The aic7xxx error handling is still very unreconstructed and DV takes
the driver through this if there's a mismatch.  My best guess is that
like Gr\'egoir's CD-ROM, your wangtek is claiming to support a speed it
cannot.  We find this out in DV, but not until we've gone through all
the error paths.  The quick fix is simply to set the bios to whatever
the tape eventually configures with (although you'll need the current
patch set to make that work properly).

Well, I can't seem to find the right collection of patches applying
cleanly on 2.6.12-rc6 and the Adaptec BIOS says "ASYNC". It cannot
go below 10MB/s and the tape unit can't go above 3.3 according to
/proc/scsi/aic7xxx/0 I think:

Target 4 Negotiation Settings
        User: 6.600MB/s transfers (16bit)
        Goal: 3.300MB/s transfers
        Curr: 3.300MB/s transfers
        Channel A Target 4 Lun 0 Settings
                Commands Queued 61
                Commands Active 0
                Command Openings 1
                Max Tagged Openings 0
                Device Queue Frozen Count 0

So, I'm kind of stuck with a very slow driver initialization. I think it
takes much longer than the 30 seconds visible in the logfile, at least
that's the impression I have (I'll use a stopwatch next time).

The -rc6 aic7 driver needs just over 7 minutes to recover from this tape
unit. In -rc3 this was 80 seconds. -rc2 had no problem.

I don't really need this old tape unit and I don't [re-]boot that often
so it is not a problem for me. Anyway, if something needs to be tested
then mail me a patch (for stock rc6) and I'll try it.

Well, the patches to try are the scsi-misc ones:

Not an improvement for me: now the driver goes into battle with my other
SCSI device, a CD burner. It hangs completely during boot, no alt-sysrq-anything.

Screen capture at hanging point, see http://www.frankvm.com/tmp/hang.jpg

This would be why ... you need to set you bios to 10MHz narrow (it's
currently set to 40MHz wide).

No luck doing so. I tried 10MB, 5MB(8 bit), booting UP (I have a dual
PIII 450), it doesn't really seem to make any difference.

I've set the aic BIOS back to über speed (80MB, wide negotiation)
everywhere and booted 2.6.11-rc5 again:

It works !! Thanks.

So are these patches getting into -mm first or -rc5 ??

Damn, I knew you were going to ask that ... the problem is it's the last
in a long line of invasive adaptec patches that sit in my scsi-misc-2.6
tree ... I suppose we can't have the aic driver slightly hosed for
2.6.12; I'll see if I can extract them.

You actually thought you could get away with that ?? :)

Seriously, scsi takes a long time to boot even normally, but with this
bug, it takes forever and a few more retries before it finally boots up.

I would really appreciate if you could extract and send them upstream,
Thanks

James,

This also solves my problem that I reported in this thread

OK, I think the patch below is the extract of this.  Could you see if it

This doesn't seem to fix the problem :(
I tried both 2.6.12-rc4+patch and 2.6.4-rc4-mm1+patch

This is what I get

Well ... great, it doesn't work for anyone, sigh.

OK, could you try this one (also against vanilla 2.6.12-rc4).  Hopefully
it's a rollup of all the aic7xxx changes plus the necessary supporting
infrastructure in my scsi-misc tree.

If it works, trying to get it into a patch set for Linus is going to be
a right pain ...

James,

It does work with the exception that my u160 drive is still identified
as 80MB/s.

OK, it looks like the period is limited to 25ns.  Could you confirm
this?

cat /sys/class/spi_transport/target0:0:0/period
cat /sys/class/spi_transport/target0:0:0/max_period

Now, if the max_period is 25, try doing

echo 12.5 > /sys/class/spi_transport/target0:0:0/max_period

and then

echo 1 > /sys/class/spi_transport/target0:0:0/revalidate

to trigger a revalidation of the domain and see if it comes up to 160.

Thanks,

James

this doesn't exist, but i bet you knew that

actually put this into period but it didn't take :-( period is still 25
and before you ask min_period is 12.5

did this anyway and this is what i got

May 19 20:21:45 porky kernel:  target0:0:0: Beginning Domain Validation

Any idea why I can't set the period to 12.5? I am going to see if
anything jumps out at me.

Doh, sorry, brain malfunction.  That should be min_period ...

what's the dt setting? if it's zero, try setting it to one and then
lowering the period to 12.5 but don't trigger a revalidate this time,
try reading or writing to the disk and then see what the settings come
back as.

the dt setting is 0. can't set it to 1, at least not so that you can see
it stay that way. tried setting period to 12.5, stays at 25. min_period
is set to 12.5 but doesn't seem to matter. what's next :)

Well, I think it's my fault.  I naively assumed the aic7xxx core setting
code would do the right thing with coupled parameters, which, as I read
through it, apparently it doesn't do.

My excuse is that I can't test any of this because my fastest aic7xxx
card is only a U2 ...

Could you try this, I think it does the correct thing with the coupled
parameters.

Thanks,

James

Even with the patch that you posted last night something still isn't
quite right. Notice in the output below that the faster drive is setup
at 80MB/s instead of 160MB/s. It's like going back to the days before
U160 stuff worked properly :)
