Red Hat Bugzilla – Bug 214402
Kernel BUG at lib/list_debug.c:31 invalid opcode: 0000  SMP
Last modified: 2008-08-02 19:40:36 EDT
Description of problem:
I just happened to notice it in /var/log/messages this morning.
The system was rock solid stable with a single core AMD64 processor. After
updating to an X2 processor it is not as stable. There was occasional drive
errors, lockups with FC5. The system seems much more stable with FC6. Still
getting occasional random lockups in X when using Firefox.
Let me know if I can provide any more helpful details.
Version-Release number of selected component (if applicable):
Have not tried to reproduce it.

This appears to be a duplicate of Bug #198350. I've attached my own log output
I've seen the same error on both a dual-Opteron 270HE and a virtual machine with
just a single CPU allocated. The host system is able to keep running with the
other CPU's taking over; the single-processor vm locks up hard.

Add an INIT_LIST_HEAD()
Trevin, I don't think this is the same as yours. Both bugs are list related
but I don't think they have the same root cause.
I looked through the code but it doesn't seem like INIT_LIST_HEAD() is ever
called so the ->prev and ->next pointers would be bogus. I've attached a patch
to fix that.
I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the Fedora kernel.
I am CC'ing myself to this bug, however this version of Fedora is no longer
Please attempt to reproduce this bug with a current version of Fedora (presently
Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a
few days if there is no further information lodged.
Thanks for using Fedora!
Closing per previous comment. If you can provide the requested information,
