Description Doug Chapman 2006-07-12 17:18:01 UTC 
Description of problem:
Seen on one of my HP ia64 Integrity servers running a proprietary HP test suite.
   Since all the messages are rather lengthy I wil upload it as an attachment.

But here are some of what think are the more interesting messages:

Slab corruption: (Not tainted) start=e0000040765c2828, len=104
kernel BUG at mm/slab.c:608!
kjournald[541]: bugcheck! 0 [1]

....
slab error in slab_destroy_objs(): cache `bio': start of a freed object was
overwritten


Version-Release number of selected component (if applicable):
kernel-2.6.17-1.2364.fc6


How reproducible:
This took about 10 hours of stress testing before it was seen.  I will update
this BZ if I see it again.


Steps to Reproduce:
