Previous frame inner to this frame (corrupt stack?)

The code path in this backtrace is very low-risk, there are not many
things that can go wrong in a gettimeofday() call. It's very likely it's
a hardware problem (tried memtest86 recently?), but you should post it
to current@ to verify. You might want to switch to TSC timecounter if
it's available on your hardware (see kern.timecounter.smp_tsc) to avoid
the acpi_timer* code path and see if the system still panics.
