>Environment:

	Stock 3.4-RELEASE; no patches.
        Custom kernel config - can provide if deemed relevent.
        tcsh-6.09.00 - from 3.4 packages
        /dev/fd0 is a 3.5" floppy drive

>Description:

	In an xterm running tcsh, I mounted a DOS floppy using:
        
             sudo mount -t msdos /dev/fd0 /a

        The floppy mounted.  I was able to ls the root directory.  No
        problems so far.

        Then in my shell I started typing a command to copy a file off
        the floppy:

             cp -p /a/

        At this point I hit Ctrl^D to get a directory listing of the
        available matching files (bound to the tcsh
        delete-char-or-list-or-eof function in tcsh, as is standard; type
        "bindkeys" to check).

        The machine completely froze.  The X mouse cursor was dead.
        Ctrl-Alt-Backspace would not quit X.  Ctrl-Alt-Del would not
        reboot the machine.  Attempts to switch VTYs were ignored.
        No response for anything I tried.

        I hard-booted and (after much fsck'ing) checked the 3.4 errata.html
        file on freebsd.org, and then sent this PR.

>How-To-Repeat:

	Perform the above action and see if it happens for you.  

        I'm hesitant to try tcsh matching files list on a floppy again
        right now (I need to get a full backup made).

>Fix:
	
	Unknown.

  More info:
  
  After rebooting, as root, I mounted the floppy again and started a
  recursive copy off it using:
  
       cd /a; tar cvf - . | (cd ~/mydir; tar --unlink -xpf - )
  
  (in a script I use).
  
  It looked like it was going well, I got my prompt back, and did a "umount
  /a" (while the floppy light was still on fwiw).  After a second or two,
  before the umount command came back, the machine froze again.  A hard boot
  was req'd to get control of the machine.
