>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.

I can reproduce this in -current as well.
(run a ping against the machine where you try to mount the floppy - the
problem is obvious)

Problem also occurs in the 4.0 RC5 kernel.
