It probably depends on the amount of memory installed and the BIOS
version. Basically the crash happens when the kernel tries
to duplicate MTRR setup done by the BIOS to the other CPU, so likely
there is some issue in the original MTRR setup.

I haven't heard a report for it from the V810 at suse, perhaps
it doesn't show it.

There is a bug open for the issue, but I haven't had time to look
at it in detail yet.
