Hi
I run OpenBSD 4.3-stable on a soekris net-5501.
Today I was dumping files from a wd0 disk to a mountpoint on sd0 disk
(external USB). I "accidently" unplugged the power cable of sd0 disk and
my system paniced. I think this should not happen, so here are some more
details:
This is my dmesg:

I attached my serial cable and saw the ddb prompt. I don't know what's
above the ddb. But, here's ps and trace.
