Package: sshfs
Version: 2.2-1
Severity: important
I had mounted another computer via sshfs, the logged out.
Next time I logged in, any process that touched the mountpoint
would hang forever. "ls mountpoint" would hang, as would
"ls -l $HOME" where mountpoint is in my home directory.
This all started within the last few days.
Along with the hanging, dmesg reports massive problems:
