BriQ & Linux 2.6

BriQ & Linux 2.6

[Jamie Heilman]

I attempted to boot a 2.6.6 kernel on my BriQ today and ran into a
snag... it appears that the IBM,CPC710 PCI bridge handling stuff
didn't make it into 2.6.  As such the host won't boot as all the
goodies hanging off the PCI bus vanish.  Any plans to roll the code
forward in the near future?

I have a few patches for the briq, I didn't push them upstream yet,
as I'm trying to find a clean way to deal with an issue relative
to the serial port clock setting.

Enclosed is my latest version of that patch (may need some hand-applying
as it's a couple of monthes old).

Ben.

What is that issue out of curriosity?  I ask because... well I've had
some rather incongruous experinences with serial on the BriQ compared
to what Karsten at Total Impact was telling me I should be having.
Basically, all the kernels they've shipped recently had code that did
some funky stuff to the baud rate.  On my briq that made the serial
port spew total garbage during boot until init hits runlevel 2 and
resets it (debian), then everything is OK again.  After reverting their
changes everything works again.  So I'm afraid I've had to take their
code with a grain of salt.  ISTR they were multiplying something by 4
that I found was better left alone... but I'd have to go back and see
if I could find my old source trees to be sure, last time I looked at
this box was 2 years ago.

Well... the base clock isn't what the driver thinks, so it must be
hacked. But the driver doesn't provide a clean way to set another
base clock, I'm trying to find something better than what the hack
in the patch does.

Well progress so far, I have 2.6.6 booting now, had to fumble a little
to apply one chunk but the rest was easy.  Problems so far: during the
entire boot, my console is line-noise-like hash[1], until runlevel 2,
then it starts behaving correctly.  The NICs (I have the PCI
expansion + extra NIC board) are having some issues....

          RX packets:118521 errors:0 dropped:0 overruns:0 frame:0
          TX packets:1 errors:57244 dropped:0 overruns:0 carrier:57244

...and yet, strangly I don't seem to be having any obvious network
performance problems.

Now this isn't the first time I've had issues with either of those,
and I think there are some patches in the Total Impact kernel source
for the NIC issue.  So I'm definately a lot closer than I was.

    but then all the kernels from Total Impact do the same thing, and

Linux console starts at 9600 while the briq firmware use a different
speed (I don't remember which). Try adding the speed ot the kernel
command line

console=ttyS0,<speed>

For example

console=ttyS0,38400

Interesting. I keep seeing reports of problems with pcnet32 driver,
that's weird though.

Sure ... ok I see whats going on, ages ago, when my briq ran 2.2 it
was always spoken to at 38400, but the kernel seemed to think it was
actually 9600.  As long as everything (init, setserial, getty, kernel)
agreed it was 9600 but you actually connected at 38400 all was well.
Now I see that things are trying to present a truer picture.  I still
had everything set to 9600, so the kernel was running at true 9600
and was garble, but init and getty would work OK.  I just poked
at my apps, now they all agree on 38400 and everything works now.
So that explains that, misconfiguration on my part; easy fix.

Yeah, quite.  It doesn't do that using the 2.4.24 kernel from TI,
which has pcnet32.c version 1.27a.  There have been a lot of changes
since then though.  The only one that caught my eye was that back then
the 79C973 was flagged to activate tx error recovery, and in the newer
driver it isn't.  I might play around with that and some higher
debugging levels later.

Right now the more immediate problem is that any amount of disk IO
that approaches significant triggers an immediate reboot.  Which is
obviously not cool.  I'm doing some SMART tests on the drive, we'll
see if that has any interesting feedback.

Re: BriQ & Linux 2.6

[Jamie Heilman]

Well played around with the pcnet32 driver, reverting some of the
changes since 1.27a, and it didn't help at all, so I gave up on that
problem and focused on the spontaneous rebooting.  SMART tests on the
disk revealed nothing, acording to the selftests everything is fine.

On a whim I removed the gargoyle expansion board from the briq, and lo
and behold - stability improved dramatically.  Its hard to know why it
helped.  But more disturbing is that it didn't solve the issue by a
long shot.  So I ran bonnie++ for a few itterations ... and it worked
flawlessly (in 2.6.6-bk8).  Then I ran:
while :; do tar jxf linux-2.6.6-bk8.tar.bz2; echo -n .; done

The second time through the machine spontaneously rebooted.  :-(
So I booted up 2.4.24-2004021601briq from TI's site, reran the above
test, and it got through about 4 itterations before it locked up hard,
and VFD went dark (didn't reboot).  So then I stepped back to
2.4.23-2004012801briq also from TI... ran the test again, got maybe 1
itteration further and locked up again.  So, swearing up a storm, I
booted up 2.2.19 and ran the test again, this got through quite a few
itterations (like around 11 or 12) but in the end the machine still
locked up and the VFD went dark.

Frustrating; I'm starting to wonder if the software is the real issue
though.

Picked this patch somewhere, let me know if it helps for the bogus
Tx errors. I don't know what's up with the lockup at this point, I
would expect the machine to be stable. Can you try to exercice it
using only netbooting instead of the HD or switching the HD down
to PIO mode (hdparm -d0 /dev/hda) to try to isolate the source of
the problem ?

Ah cool, thanks I'll give it a try.  It'll be a while though, I just
accepted a job out of state, so I'm starting the moving process and
one of the first things I did was stick the briq back in its box.
It'll probably be a month before I'm ready to pull it out again, but
I'll let you know how it goes when I do.
