Hi folks,
my kernel just oopsed on me - that was quite some time ago...
Linux kernel 2.0.36pre15, no additional patches, using the fdomain SCSI
module.
I had a rewritable CDROM in my Philips CDD3600 SCSI CDROM Rewriter, and had
it mounted under /mnt/cdrom. I then umounted it, removed it, put a recordable
CDROM in the player, and tried to mount it under /mnt/cdrom. At that moment,
the process hung (it could not be killed), and syslog showed the following
output:
