Version-Release number of selected component (if applicable):
kernel-2.6.26.5-45.fc9


How reproducible:


Steps to Reproduce:
1. Install lastest kernel 2.6.26.5-45.fc9 (latest Fedora 8 kernel 2.6.26.5 has also this bug).
2. Configure openswan.
3. You will get kernel crash with the above on the logs in several hours or days.
  
Actual results:
Kernel crashes on machines with openswan configured.

Expected results:
Kernel does not crash.

Additional info:
I am not sure, but it looks like the slower machines crashes more frequently.
