Description Lonni J Friedman 2006-03-22 23:25:20 UTC
Description of problem:
At some random period of time after booting up a system with the dave jones
2.6.16-1.2070_FC5 kernel, I'm seeing a spontaneous Oops.  

Version-Release number of selected component (if applicable):
2.6.16-1.2070_FC5

How reproducible:
Install 2.6.16-1.2070_FC5 and boot into it.  Wait anywhere from 5 to 15 minutes,
leaving the system sitting idle in run level 3

Steps to Reproduce:
1.Install 2.6.16-1.2070_FC5
2. boot into 2.6.16-1.2070_FC5, runlevel 3
3. leave the system idle for a few minutes (anywhere from 2 to 15)
4. Oops!

Comment 1 Lonni J Friedman 2006-03-22 23:29:50 UTC
I should add this is happening in a Biostar TForce 6100 motherboard.

Comment 2 Dave Jones 2006-03-24 23:20:34 UTC
please reopen if reproducable without the tainting module.
