Comment 55 for bug 616287

ingo, I just noticed that your ssh.conf has

stop on runlevel S

That was fixed in maverick under bug #603363, and accepted as an SRU we need to push back to Lucid. That won't *solve* this definitively, as sendsigs/umountfs might still beat openssh in the race condition because of bug #688541, but it should help. Until that SRU is done, you can manually change it to 'stop on runlevel [!2345]'.

Not a solution, but it should reduce the likelihood of preventing umounts from completing.

And to everybody who is participating, thanks for posting your greps, it helps!
