Hello,

first, thank you for your great work on the kernel!

Second, I have an issue:

I tried 2.6.29 but my maschine is always freezing after 2 minutes
and about 10 seconds running.

So I bisected that beast and found the cause (?):

commit 1e91477aa335fc1c97eb15649ed1a1714cc758ec
Author: Borislav Petkov <petkovbb@gmail.com>
Date:   Tue Jan 6 17:20:57 2009 +0100

    ide-cd: start DMA before sending the actual packet command

    as it is done for all other IDE ATAPI devices.

    There should be no functionality change resulting from this patch.

I tried to revert this patch in 2.6.29 but the revert produced a merge
conflict and I don't have the knowledge to resolve this conflict.

So as a quick workaround I disabled ide-cd in my kernel config:

# CONFIG_BLK_DEV_IDECD is not set

which does the trick but is of course no solution. (I'm writing
this email with 2.6.29 and disabled ide-cd.)

My CD is a ide dvd drive attached to an promise pci-controller:

Well, its kinda strange that this piece of code could be the problem
since the bits it touches are gone (this'll explain the confict when
attempting to revert the patch.) Can we please see a dmesg of a working
kernel on your machine and also is it possible to catch any kernel
output of the crash, any oops or something when your machine freezes -
the more the better. Probably over a serial console would be best but
photographed with a digicam and uploaded somewhere as a screenshot would
do too.

You could also try the following patch to see whether that is of any
help:

Hello Borislav,

thank you for your help.

Sure, dmesg output appended beneath. I also added the dmesg output
of the patched kernel. See below.

There aren't any messages, neither on the console nor in the syslog.
The kernel simple freeze, cursor on the console stops blinking, no
more ide activity. I have to hit the reset-bottom to restart.

I will do that on request, but it will take some time (about days)
because currently I don't have access to a second computer or so.

Your patch helps perfectly. I'm writing this email on the patched
2.6.29. I also tested CD and DVD access: They work well. Burning not
tested but I assume it will work too.


Ok, here the dmesg of the original 2.6.29 with deactivated idecd:

That'll definitely be very helpful since I wanna know exactly why it
locks up. If you still have no output it'd be cool if you could enable
ide-cd debugging and retry catching the output. Here's a patch for that,
just recompile and reboot (I admit this is not one of the finest ways to
enable debugging but since this is work in progress...:) ):

@Bart: can you take at look at this. Somehow, if the device is behind a
PCI IDE controller, the order of issuing the command and enabling DMA is
important. Seen something like that before?

Hello Borislav,

I got even no output over the serial console when the kernel freeze. So
I tried your patch and the complete log from the boot to the freezing state
is attached below.

One additional observance: Without your hotfix starting /usr/sbin/hald
takes quite longer (about 3 to 5 seconds) compared to about a half second
with your hotfix. Same behaviour with the commit found by bisect: Before
that commit hald starts fast and from that commit hald takes some seconds.

To me it looks like that probing (?) by /usr/sbin/hald maybe left the ide-cd
in some erroneous state which result in a freeze after about 2 minutes?

Hello Borislav,

I made two more tests:

a.) unpatched 2.6.29, boot with dvd in drive and starting
    /usr/sbin/hald by the init scripts results in a freeze
    in 2 minutes and about 10 seconds.

b.) unpatched 2.6.29, boot without a medium in an drive
    but _not_ starting /usr/sbin/hald result in _no_ freeze!

I can also mount DVDs and access them, with an unpatched kernel
without started /usr/sbin/hald, without any problems, as far
as I can see.

Used hald version is 0.5.11.

Hopefully these observances will help somehow.

c.) I unmounted the DVD, started /usr/sbin/hald and it took
    about 40 seconds until the kernel freeze.

So far as I see, /usr/sbin/hald somehow triggers a bug. But the bug
isn't triggered, when the dma is started after the command is sent.

Spec is unclear on the ordering but empirically it seems that some hosts
may need packet command to start DMA.  I think that we should proceed with
your patch (please repost with patch description) and also apply the same
change to the rest of ATAPI devices in a subsequent patch.

Thanks,
Bart

Why two patches, do we really need to differentiate between ide-cd and
other ATAPI devices? Besides the patch is so simple: 4 lines moved up.
Anyway, I lightly tested it with ide-cd and ide-floppy and both seem to
take it ok. Also, if I remember correctly, the original ide-cd behavior
was to issue the command and _then_ start DMA so we're back to that. I
guess now we should be concerned whether the other ATAPI devices can
handle the reverse situation where you first issue a command and _then_
start DMA.. Hmm...

Subject: [PATCH] ide-atapi: start DMA after issuing a packet command
MIME-Version: 1.0
Content-Type: text/plain; charset=utf-8
Content-Transfer-Encoding: 8bit

Apparently¹, some ATAPI devices want to see the packet command first
before enabling DMA otherwise they simply hang indefinitely. Reorder the
two steps and start DMA only after having issued the command first.

Most devices don't care but you do need to follow the exact ATAPI spec.
If you search way back through the archives you'll find long discussions
on this during either 2.4 or 2.2 when HP hit problems caused by us
turning DMA on too early.

AFAIK, the old bevavior was to start DMA _after_ issuing the command _only_
for CD-drives and for the remaining ide devices the other way around,
why not just restore the old behavior and do the DMA after command only
for CD-drives?

because common atapi code should adhere to the spec, as Alan said, no matter
whether it is a cd or a floppy or [you name it]-drive.

@Alan: I guess you refer to
http://lkml.indiana.edu/hypermail/linux/kernel/0305.1/2241.html, for example.
I think I'll be on the safe side when I turn on DMA _after_
writing the ATAPI command packet into the data register - it is the correct
order of steps according to the ATA spec. So, if there are devices which still
choke on that, then they're simply buggy and those will hopefully be a small
number so that a blacklist with a flag as a workaround would be more or
less ok for them - we do that for other b0rked devices anyway.

Good engineering practice -- we've changed only ide-cd in 2.6.29 so we
should start with reverting the change and backporting it to -stable.

Fixing other ATAPI devices can be handled later and preferrably after
testing them first -- who knows if there are no devices which depend on
the reverse order of doing things or that it won't uncover/trigger some
other problem.  Feel free to call me (over-)paranoid... :)

However based on later comments from Alan and the current libata code
I feel that we should be pretty safe in this particular case so we may
as well fix everything in one go.
