Ok, that expiry time is obviously bogus as it does not account the offset:

So in reality it's: expires in: 6063592890015ns

Which is still completely wrong. The timer should expire at max a
second from now. But it's going to expire in 6063.592890015 seconds
from now, which is pretty much explaining the after 2hrs stuff got
going again.

But the real interesting question is why he heck is that timer on
CLOCK_REALTIME ???? It is initalized for CLOCK_MONOTONIC.
/me suspects hrtimer changes to be the real culprit.

John ????
Thanks,
