3 weeks ago:
I upgraded from 7.1-PRELEASE to -stable and all seemed fine until I rebooted
out of single user mode after doing make installworld and mergemaster. At that
point, near the end of the boot sequence I got a core dump, apparently
triggered by devd.

Fatal trap 12: page fault while in kernel mode.
cpu id = 0; apic id = 00
fault virtual address = 0x3030313a
fault code = supervisor write, page not present
[snip]
current process = 355 (devd)

I redid the *whole* process in single user mode, yet no difference. I was out
of town for 2.5 weeks after that, then busy for a few days, which brings me to
now:
TODAY:
I booted to my memtest86+ CD, let it run through which it did with no issues
noted.
I blew away my /usr/src and resynced as of about noon today. After following
through all steps to rebuild, I now get a fatal trap 12...

Same virtual address, different process. Umm. Interesting.
I'm at a loss. Google's been of little help, and searching these lists hasn't
turned up much either.
Does anyone have a further recommendation on what to do, try, test or change?
BTW, I'm GENERIC.
