Comment 11 for bug 614731

I had this problem in 10.10, and now in 11.04. I'm mounting a dir other than home and on wired network.
I managed to work around this by stopping autofs on shutdown and reboot:

sudo update-rc.d autofs stop 25 0 6 .

No ill effects till now (can't imagine what would be worse than having to press the power button...)

Bye
