Initially I tried sending both active and sleep sets, but as they are
not cached like in downstream (yet) i got hangs during boot. Disabling
caching in downstream kernel also caused the same hangs, so i left
this out for now. Will try debugging it further.
Will fix the rest according to your comments. Thank you!
