Console/terminal hangs on mount, sync & shutdown
I have no clue what's going on here, but a few hours ago I tried to mount a USB drive:
$ mount /mnt/usb
and the terminal halted. Nothing worked: Ctrl-C, kill... Ok, I forget about it, no matter I can't access the important data on it I need before I go on holiday (just within a few hours). So an hour ago I wanted to shut the machine down using
$ sudo shutdown -h now (called from an X menu)
The console appeared with the well-known message that the "system is going down for system halt NOW!" message, accompanied by its fellow "waiting for X server to shut down". Again, nothing. So I went back to X and logged out (I don't use xdm/gdm/whatever at the moment, just a console login).
To vc 2, logged in as root, tried 'reboot'. Again, nothing.
Ok, let's try at least a sync. Logged in as normal user on another vc, issued 'sync', guess what...
Hmmm, how do I safely shut down this computer without bluntly pulling out the power plug? Just some more info:

Re: Console/terminal hangs on mount, sync & shutdown
I have the exact same problem at the moment. rtorrent was running, I wanted to restart it. I can't (it won't die now matter how I try to kill it).
Tried a "sudo reboot", which does nothing.
