Hi,

On a -stable buildworld from 19th of november, when I try to write to an
msdosfs partition, the computer instantly hangs for 3-4 seconds and then
reboots. Upon inspection after reboot, an 0-byte file was created, but I
cannot delete it without crashing yet again.

I can't get any debugging info, there's nothing in the log, it just
reboots. I don't think this is a hardware failure, because Windows
doesn't give a hitch, but it could be some edge case FreeBSD is hitting
and Windows isn't. Dmesg is attached.

Can anyone reproduce this?
