Kernel next, this is the first bad commit ( after bisect ):

e4bc13adfd016fc1036838170288b5680d1a98b0

Merge branch 'for-4.2/writeback' of git://git.kernel.dk/linux-block

After the command to unmount, partition will be unmounted, truecrypt hangs

Yeah, there's a bug with bdi_writeback_congested handling.  There are
fix patches pending.
