#11 incomplete shutdown after use shfs

[Jean Pierre Grazi]

I am new to linux and new using shfs.... sorry. My
computer has the following behavior with shfs:
After use shfs the shutdown process get freezed. After
the TERM signal ti says Turning off swap and it
freezes. It downs the network and deactivates the
keyboard. I tried with init 0 and init 6 with the same
results. The last message found is "interface not
available and no configuration found" At that point I
should turn off the computer manually and it gets many
errors when it boots again.
Any ideas? is that a shfs bug?
thanks
