I wonder if it could be a problem with the BIOS not setting up the MTRR registers correctly. I have seen problems (on SMP machines) where the BIOS was not setting up the MTRR registers on some of the CPUs weren't caching any of memory. FreeBSD has a work around for this in the SMP case, but maybe not in the single processor case. I'd try looking for a BIOS upgrade, as it may be a problem with the old BIOS not initialising the new processor. David.
