freebsd stable - Aug 2009 - (no subject)

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...

****
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 = 352 (sysctl)
****

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.

Do you have any kmod's from ports on that system? Loaded in loader.conf
maybe?
If so, try to no load them and see what happens.
