Description Lucas Maneos 2006-10-15 18:28:37 UTC

Description of problem:

When booting FC 5.92 on an EPIA EN1200 board the kernel panics.  I can't capture
the console output, but the call trace in the screenshot at
<https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.17/+bug/63134> is
exactly what I'm seeing (modulo timestamps & offsets).

Finally managed to boot the machine with pci=off, did a basic installation and
recompiled the kernel with the contents of the quirk_via_abnormal_poweroff
function commented out, which fixed the problem.

Version-Release number of selected component (if applicable):

Problem is present in all kernels I've tried between whatever version the 5.91
installer comes with and 2.6.18-1.2784.fc6.  5.90 boots fine (but I couldn't get
much further with it due to installer bugs).

How reproducible:

Every time.

Steps to Reproduce:
1. Boot 5.91 or 5.92 installation media or netboot
  
Actual results:

Kernel panic.

Expected results:

Successful boot.

Comment 1 Dave Jones 2006-10-16 17:55:42 UTC

For the release kernel for FC6 (which I'm building today), I've removed this
function.  I'll chase it upstream and see if I can get a better fix out in an
update.

Just to confirm, kernel-2.6.18-1.2798.fc6 boots ok.

Comment 4 Dave Jones 2006-10-18 07:22:06 UTC

turns out ACPI is already doing the same thing. So it looks like upstream will
also be removing this function.

Lucas, Can you clarify if this means that 2.6.18* always works,
or that at some point it workes and some point it failed like
2.6.17 did?

Comment 6 Lucas Maneos 2006-10-21 23:01:00 UTC

2.6.18-1.2784.fc6 also panicked, until I rebuilt it with
quirk_via_abnormal_poweroff() neutered.  There are no other 2.6.18 kernels in my
yum.log.

Comment 7 Len Brown 2006-10-22 18:25:13 UTC

Thanks, and kernel-2.6.18-1.2798.fc6 worked without any modification?

Comment 8 Lucas Maneos 2006-10-22 22:50:53 UTC

Yes, unmodified straight-out-of-the-rpm kernel-2.6.18-1.2798.fc6 boots without a
panic.
