Hi Milan,

Thank you for your explanation.

So I'll try to find logs regarding this issue (won't be easy though..).

On the other hand, the usb device survives suspend/resume normally, that is,
when using a plain disk, std partition etc.

Ok, I'm going for the logs and if found be back.

Thank you again for your help.

Nils

# So instead of "cryptsetup luksClose" use dmsetup remove for crypt device too
# (There was a bug in some version of cryptsetup which failed close if underlying device
# disappeared, should be fixed in >=1.1.2, anyway "dmsetup remove" is low-level equivalent.)

# Also see man page and "dmsetup remove -f" flag.
