echo disk > /sys/power/state broken

Hello all

After recent update after long time my hibernate was broken

#echo disk > /sys/power/state
does black screen and standby of display later. But system block not turned off, e.g. fans are worked.

#echo mem > /sys/power/state
is working. Before update echo mem not worked right

#cat > /sys/power/state
freeze mem disk

Install old kernel not resolve the problem.

I try to do debugging hibernation with https://www.kernel.org/doc/Documentatio … ugging.txt
echo freezer > /sys/power/pm_test
echo disk > /sys/power/state
worked
but
echo devices > /sys/power/pm_test
echo disk > /sys/power/state
not worked

If the "devices" test fails, most likely there is a driver that cannot suspend
or resume its device

Who can broke hibernation process?
