>Description:
When trying to mount a floppy drive, with no floppy inserted in the drive, X freezes for a few seconds, the unfreezes, then freezes again. This is looped a few times (you can see in the dmesg output shown below) until a hard error is printed in dmesg. I used the command:

--
# mount /mnt/floppy
--

In my /etc/fstab:

--
/dev/fd0a	/mnt/floppy	msdos	rw,noauto	0 0
--

dmesg gives:

--
fdcresult: timeout
fd0: timeout (st0 20<seek_cmplt> cyl 0)
fdcresult: timeout
fd0: timeout (st0 20<seek_cmplt> cyl 0)
fdcresult: timeout
fd0: timeout (st0 20<seek_cmplt> cyl 0)
fdcresult: timeout
fd0: timeout (st0 20<seek_cmplt> cyl 0)
fdcresult: timeout
fd0: timeout (st0 20<seek_cmplt> cyl 0)
fdcresult: timeout
fd0: timeout (st0 20<seek_cmplt> cyl 0)
fd0a: hard error reading fsbn 0 (st0 20<seek_cmplt> st1 0 st2 0 cyl 0 head 0 sec 0)
--

After this, the freezing stops. I insert a working floppy, and try to mount once again (using the same command as above). The freezing occurs again (though fewer times), and dmesg gives:

--
fd0a: soft error (corrected) reading fsbn 0
--

The floppy is then properly mounted. I can read data from it just fine. The unmounting of the floppy works fine, and subsequent mounts/unmounts work properly as well.
