Here is a trace from an oops that occurred with the debug kernel. The trace
occurred while heavy I/O was taking place.

Some more observations.
- When I run system repair from the install DVD it always complains about a
corrupted XFS partition, even if I run repair pretty much right after install
- System might also just hang and no dump is triggered, when the system goes
into never never land keyboard LEDs for caps lock and num lock blink, this
behavior has been observed when removing large directories from disk or
unpacking large tarballs (> 1GB)
- Running mem test on the machine triggers no errors (let mem test run for 16
passes)
- Running firmware test triggers 4 failing tests:
~ [FAIL] OS/2 memory hole test
The memory map has a memory hole between 15Mb and 16 Mb
~ [FAIL] MTRR validation
many addresses with "has incorrect attribute write-back
~ [FAIL] HPET configuration test
Failed to locate HPET
~ [FAIL] EDD Boot disk hinting
Boot device 0x80 does not support EDD

Additional info:
~ I run 11.2 on 2 laptops with Centrino Duo (i.e. 2 core processors) and am
also using XFS. Unpacking the same large tarball and remove operations similar
to those on the flacky desktop machine do not trigger these types of errors

The hardware:

Intel Core 2 Quad Q6700
8 GB DDR3 memory
1 TB SATA drive
