quirk_via_abnormal_poweroff causes kernel panics on (some?) EPIA boards at boot time
Last modified: 2015-01-04 17:29:05 EST
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
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).
Steps to Reproduce:
1. Boot 5.91 or 5.92 installation media or netboot
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

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
2.6.18-1.2784.fc6 also panicked, until I rebuilt it with
quirk_via_abnormal_poweroff() neutered. There are no other 2.6.18 kernels in my
Thanks, and kernel-2.6.18-1.2798.fc6 worked without any modification?
Yes, unmodified straight-out-of-the-rpm kernel-2.6.18-1.2798.fc6 boots without a
