Hi,
Kernel 2.4.12 is no more able to handle two floppy drives with hfs
formated floppies.
You can recreate the failure if you have two floppy drives, use Kernel
2.4.12 (and above) with loadable module support for hfs- and
vfat-floppies and try to mount the first one with a hfs formated floppy
inside. If you unmount the floppy drive again you will get a
segmentation fault and an uninterruptible sleep for the mount PID. You
cannot mount this drive again.
For all other see attached file 'report'.
Regards
Wolfgang Pichler

Kernel 2.4.12 is no more able to handle two floppy drives with hfs formated floppies.
You can recreate the failure if you have two floppy drives, use Kernel 2.4.12 with loadable module support for hfs- and vfat-floppies and try to mount the first one with a hfs formated floppy inside. If you unmount the floppy drive again you will get a segmentation fault and an uninterruptible sleep for the mount PID. You cannot mount this drive again.
The syslog message for the mount command is quiet normal:
Nov 15 13:23:43 pc kernel: VFS: Disk change detected on device fd(2,0)
Nov 15 13:23:46 pc kernel: FAT: bogus logical sector size 63222
Nov 15 13:23:46 pc kernel: VFS: Can't find a valid FAT filesystem on dev 02:00.
The syslog message for the umount-command is:
