The weird thing is that there is no problem if I turned on the debug
option. I can see kcryptd taking 99% CPU time and there are many
debug output from the serial port, but the encrypted LVM worked eventually.

In some cases the non-debug version can work with "mkfs.xfs", but it
could not in most case.
I tried to disable most services in the system, but it seems have no
related to the system load.
