Sorry to hear you are having a problem.

Just to confirm, this is running on hardware and not on a Xen
hypervisor, correct?

Assuming it's running directly on the hardware, can you see if setting:
hw.lazy_fpu_switch=1
in /boot/loader.conf makes any difference?

Is there any panic message?

Thanks,
Gordon
