------- Comment #22 from gi1...@users.sourceforge.net 2008-12-29 10:39 -------
I've had the same problem on an HP 2710p ever since 2.6.24/25. Just today I ran
it on a 2.6.28 kernel, with X86_CHECK_BIOS_CORRUPTION=y and I found the
following in /var/log/messages:

---[ end trace 2ff63db346bda773 ]---
When the system doesn't crash, the above is repeatable, and produces a
corruption in the same regions of the memory. When the system crashes, I get a
complete freeze (though once or twice I've got an Oops).
The documentation says I can use memmap to stop the kernel from using this
memory. Will try that next...
