Description Eli 2005-04-27 01:08:18 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-1.3.1 Firefox/1.0.3

Description of problem:
On shutdown, I once saw a kernel panic, uninitialized spinlock in block/cfq-iosched.c:1065

From my written notes:
Stopping cups: Kernel panic - not syncing: drivers/block/cfq-iosched.c:1065: spin_is_locked on uninitialized spinlock ed89301c. (Not tainted)

I've only seen this once, but due to regressions in other behavior for this kernel, I'm running kernel-2.6.10-1.770_FC3 for the most part.

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

How reproducible:
Didn't try

Steps to Reproduce:
1. Shutdown computer

Actual Results:  Saw kernel panic message as described above.

Expected Results:  Don't panic.

Further testing....  I can get this again on shutdown with kernel-2.6.11-1.14_FC3.
I'm not finding anything in /var/log/* about it, so I'm going by the notes I
jotted down:
I got the same kernel panic message as before, then "atkbd.c: Spurious ACK on
isa0060/serio0.  Some program, like XFree86, might be trying to access hardware
directly." scrolling on the screen.
I had to use the power button to shutdown, and the system complained of an
unclean shutdown when I powered up again.
