Public bug reported:
Binary package hint: gnome-power-manager
When I have the JACK daemon running with realtime priority on this MSI Wind
U100 laptop and pull out the wall power, the system tells me that the battery
is low and enters hibernation. The battery is full, though.
If JACK is not active, nothing happens (just the battery symbol goes gray,
which is irritating, but intended, I guess).
This forced hibernation is particulary annoying as JACK really does not
like going to sleep; it cannot be killed by an ordinary user after
resume (meaning: stop it via the button in qjackctl); pkill -9 jackd is
needed. But that's another bug in the JACK audio server that one could
live with, wouldn't the system -- and I suspect it's called gnome-power-
manager here -- force a suspend to disk.
I'll check again if it's really just an issue when JACK has realtime
priority, after posting this initial report (don't wanna loose it as
collateral damage). Even if it is, I suspect some nasty race condition
that could occur any time, but is helped by the scheduling schism
introduced by JACK.
