>Description:
	
Kernel: page fault trap, code=0
	Stopped at _vm_fault+0x59: mov 0x22(%esi),%ax

In this case a trace showed no more info, and attempts to c (to get a
core dump) or call _boot etc just got another page fault.

This has happend twice this week now.  kern/2673 was the only PR I
could find that mentioned _vm_fault, so here we are.

BTW, I've not yet tried the latest sources (I will), though I could
not find any sources under sys/vm which have been updated thince March
8.

Each time this has happened my overnight cron jobs result in a rash of
sh.core files - all from segmentation faults.

I'm sorry I can't provide more useful info.
