I get easily reproducable panics (supervisor read, page not present)
in today's -CURRENT; yesterday's sources with the same config works
fine. The kernel panics almost immediately if I run something that
does a lot of writing to disk, such as a kernel or port build. It
refuses to dump (dump already in progress) and I don't have a serial
console handy for DDB, so no dump or backtrace, though according to
nm(1) the page fault occurs in xpt_release_devq() in aic7xxx.c. I've
attached the kernel config and the output of dmesg (from the kernel
that works, not the one that panics).
