Hi,
I get the following repeatable panic by just doing:
# mount /cdrom
when there's no disk in the drive. The panic doesn't happen immediately,
the mount call returns and gives the error 'device not configured' (as it
should), but if I wait some time, it panics.
The system is:
FreeBSD 5.1-CURRENT #4: Sat Nov 8 01:15:35 CET 2003
I somehow suspect the GEOMified SCSI CD driver, since I can do the same on
my laptop (which has an IDE DVD-ROM) just fine.
Attached is the backtrace and the dmesg.
