Many thanks for the advice. I will try those options as well and monitor 
the machine for awhile.

After adding the 'acpi=off' option I noticed a kernel message saying 
something along the lines of "MP-BIOS bug: timer not connected to 
IO-APIC" just after the "Starting up..." line. I'm not sure if this was 
showing before I changed the kernel params but it looks related, if not 
the same issue. I see the same entry in the kernel log and dmesg now I 
know what to look for.

Regards,
Tom
