1) echo platform > /sys/power/disk; echo disk > /sys/power/state
works but prints:
BUG: sleeping function called from invalid context at include/linux/writeback.h:87

2) "s2disk" (from suspend-0.8) suspends, but doesn't resume (and I need to mkswap && swapon -a later)
It's not a regression, because I never tried to STD (STR worked).
