The kernel version was 2.6.9-11 that was patched with patch from https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=159815
The kernel was compiled for SMP i686.

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

How reproducible:

Steps to Reproduce:
1. Compile the kernel
2. Start the tests with high load (our application does mysql clustering there are lot of connections to database and CPU is used heavily. All connections will go truough ip_queue module).


Actual Results:  In 24 hours the panic will happen

Expected Results:  Kernel should continue working
