while playing with raid on vnd my current (3.99.15 as of 2006-02-07)
NetBSD/i386 system crashed. I was running X and thus had to issue the
ddb commands blindly; ddb.tee_msgbuf was set to 1, and that's what was
in the message buffer when the system was available again:

uvm_fault(0xc0893f60, 0x1e000, 0, 1) -> 0xe
kernel: supervisor trap page fault, code=0
Stopped in pid 15.1 (pagedaemon) at     0xcbae2556:     scasb   (%esi)

(The first command I issued was IIRC `dmesg', but obviously I managed
to misspell it...)

A crash dump is available in case anybody is interested.
