(Do you mean patch posted in this thread?)

Now I must admit it does happen without patch too. Sometimes it goes throug=
h=20
but most of the time it results in those timeouts.

So I confirm that patch posted in this thread fixes original problem (khubd=
=20
killed by SIGKILL).

W.r.t. to timeouts - I appreciate hints where to start debugging. (I am=20
downloading vanilla kernel + -mm to give it a try).
