Bug 5210

[please reassign to the correct component if my guess was not right. might be
ram, disk or xfs related, among other things.]

[....]

Lots of oops (attaching to the report) when disk is stressed (usually bonnie++
freezes at "writing intelligently" phase). memtest86+ was running for hours
without error. machine freezes with or without swap. disks are believed to be
good (smart, badblocks) CPU is not overclocked and temp is resonable. 

I cannot point to any hardware fault (not being familiar with kernel internals
this deep), but not impossible. 

Bonnie++ can crash it almost anytime. Did under 2.6.8.1, 2.6.12.* and does under
2.6.13 too.

Distribution: kernel.org
Hardware Environment:
Intel(R) Celeron(R) CPU 2.00GHz, 512M RAM
