Subject: Floppy: /dev/fd0 is not a valid block device

    Hi!

    I've got a SPARCStation Voyager (sun4m).
    When I try to mount a floppy (fat, vfat, ext2) I've got the following
    error message:

            mount: /dev/fd0 is not a valid block device

    In /var/log/messages the following lines are found:
            
            kernel: VFS: Disk change detected on device fd(2,0)
            kernel: end_request: I/O error, dev 02:00 (floppy), sector 0

    Also the commands fdisk, mkfs.XXX don't work.

    I compiled a new kernel (2.2.16, 2.2.17, 2.4.0-test11) with fat, vfat,
    umsdos and msdos support (according to a former posted message about
    that problem) but allways with the same result.

    The floppy device seems to be physically ok: I could boot from
    (Redhat...) Installation-Floppy (because SuSE's installation floppy
    didn't work on my machine -> bad magic number).

    Does anybody have an idea, how to fix this problem?

    Thanks a lot!

    Thomas
