Hey there. I ran into a panic last evening on my alpha 4/166, running
NetBSD-1.3.2 (I recompiled the kernel just to remove a few value-added
devices). Right after mounting a disk (the mount command didn't return) I
got a panic which told me it was "locking against itself." I have the dump
at home along with the text (sorry I can't include it in here - I'll post it
if need be). I haven't been able to reproduce it, so I'm not incredibly
worried about it, but I did want to report it in case it can help anyone.
It was a new device that I was trying to mount (not a new piece of hardware,
just a new disk on the system), and it was an older SCSI-I device. Is there
anywhere I should check, or is the kernel simply psychoanalyzing itself?
On a side note, is there a way to rescan the SCSI bus at runtime, to allow
adding/removing/hotswap of SCSI devices?
