panic: GPF in kernel

[Stefan Bethke]

Setting up new hardware (i5 CPU, 16 GB RAM) and doing a burn-in test running make buildworld in a loop.  After a couple of hours, I got this panic.  8-stable is from January, ZFS root.

Does this correlate with any recently fixed bugs, or is this likely a hardware issue?
