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.
