Subjectsuspect bug in patch-2.4.21-pre*
Date
Hi.
After patching the official kernel 2.4.20 with patch-2.4.21-pre2 or
patch-2.4.21-pre3 or patch-2.4.21-pre4 I had problems with
my dvd rom (SAMSUNG DVD-ROM SD-616), I can't mount data-cd and I can't see
the dvds. Therefore I have removed the patch and all it works well.

The error was always this:
# mount /dev/scd0 /mnt/cdrom
Can't determinate the filesystem type.


I use the ide-scsi emulation and I have the Slackware 8.1 distribution.
Sorry for my English but I'm Italian :-)
