Description Cameron Schaus 2007-06-05 17:27:35 UTC
Description of problem:

I am running the 2.6.20-2316 kernel, rebuilt with CONFIG_SPINLOCK_DEBUG and
CONFIG_SPINLOCK_SLEEP_DEBUG disabled.  I have disabled spinlock debugging on
advice from this kernel thread:

I will attempt to reproduce on the stock kernel.

list_del corruption. next->prev should be c1308018, but was 00000001

I will attach a dmesg.

Version-Release number of selected component (if applicable):
FC5 - 2.6.20-2316

How reproducible:
Once the problem manifests itself, it is 100% reproducible.

Steps to Reproduce:
Attempting to update RPMS, or general disk access on affected systems is enough
to trigger this problem on some systems.  Other systems seem ok.
Actual results:
Kernel panic.

Expected results:
No kernel panic.

Additional info:

The kernel is set to reboot on panic (after 5 seconds), but does not reboot on
this panic.
