Description of problem:
This happened on kernel .435 during a tpc-c run with swapping turned off.  It
probably wasn't good practice to do this, but here is the info:

invalid operand: 0000

EIP is at kmem_cache_reap [kernel] 0x375 (2.4.21-b1.435.entcustom)

Code: Bad EIP value.

Kernel panic: Fatal exception

The kernel was rebuild to include the megaraid2 driver patch to get rid of scsi
errors (driver and firmware going out of sync). 

Version-Release number of selected component (if applicable):
kernel .435

How reproducible:
Didn't try

Steps to Reproduce:
1. tpc-c run with swapping turned off

Comment 2 Larry Woodman 2003-09-18 11:31:58 EDT
Please reproduce this bug with the release candidate kernel that is not custom


Thanks, Larry Woodman

Comment 3 Suhua Ding 2003-09-18 15:41:28 EDT
There is a megaraid2 patch in bugzilla 102333.  We 
want to try the kernel on the Dell system and need
this patch.  Either a custom build kernel with this 
driver patch, or an updated driver with this patch
that will work with this release candidate.

Comment 4 Dave Anderson 2003-09-25 10:10:40 EDT
Because the backtrace is seemingly nonsensical, i.e., no linkage
to kmem_cache_reap(), there's nothing to work with.  Please try
the following debug kernel, which has the megaraid2 patch from 
BZ #102333 applied:

Comment 5 Larry Woodman 2004-04-21 10:56:51 EDT
Suhua, is this still a problem with the latest RHEL3 kernel or can we
close the bug now?

Comment 6 Larry Woodman 2004-11-29 15:38:02 EST
Suhua, we need to close this bug if it is no longer a problem.  Can
you verify that it is fixed in RHEL3-U4/

Closing due to lack of response.
