i got hard-freeze right after monitor goes into standby mode (blinking led on
monitor itself).
Same kernel goes into standby mode OK with nouveau driver or with modprobe
radeon modeset=0.
This was observed right after console login, but starting X before makes no
difference.

disabling pm_async (echo 0 > /sys/power/pm_async) doesn't help
setting pm_test to [devices] freezes like plain "echo standby >
/sys/power/state"
I'll attach dmesg from normal boot
