Bug 162872

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
Every so often the kernel crashes and hangs the machine.  I tried reinstalling FC4, switching to a different computer, and booting with the acpi=off kernel flag, but nothign has helped.  The crash seems to occur during heavy periods of network traffic or hard disk activity - high IRQ loads.  However, I have never gotten the computer to run for more than a couple of hours without crashing.  At first I thought it was related to NFS because that was where I was having the crashes, but after more investigating, it can happen at any time.

Version-Release number of selected component (if applicable):
2.6.11-1.1369-FC4

How reproducible:
Always

Steps to Reproduce:
1. install FC4
2. start a high irq task

  

Actual Results:  crash after a while

Expected Results:  normal operation
