[gentoo-user] mount umount and xterm freeze

[Harry Putnam]

I've been noticing the phenomena described below for a while now and
having a little trouble getting a good idea how to debug.

If I have mounted shares via smbfs or cifs and something happens to
make those mounts unusable, like the machine the shares are on is
powered down or whatever, then I have a problem.

If I happen to run a `ls' on the directory where the mountpoints are
kept (/mnt) or in other ways access those mountpoints, the xterm I'm
working from becomes unusable and the command NEVER completes.

These particular shares are on winXP machines and are mounted using
this syntax:

 mount -t cifs -o user=MYUSER%PASSWORD //harvey/harvey-g  /mnt/harvey-g

Attempts to umount the problem shares also results in a hung command
and useless xterm.  Killing the xterm manually seems to be the only
way to stop the hung action.

So far I've used the old MS refrain `reboot, reboot, and reboot' to
clear up the mounts but I'm sure there is some better way or maybe a
way to prevent this from the start.

umount -l /mount/point

Using that I see the problem mnts disappear from `mount' output
alright.  But those shares cannot be remounted following that command.

Trying to mount them following the umount -l (1 hr later).  Just hangs
the command.  However it isn't such a persistent hang and the normal
^c will kill  it.

Still I can't get to those shares without a reboot of gentoo it seems.
That reboot must clear something that probably can be cleared manually
without a reboot....

Even the above referenced reboot was frozen at the point of umounting
local fs.  Requiring a hard reboot.  

Any ideas whats behind this persistent mount problem?
