I have a machine running 7.0-STABLE/amd64 and it has suddenly
stopped booting. It just leaves me at the debugger with this message:
Fatal trap 9: general protection fault while in kernel mode
cpuid = 0; apic id = 00

The ACPI warning has always been there.
Any places of interest in the debugger? What's a likely culprit? bad RAM?
