Strange but I have no dropouts when running those patchs on my laptop
with both alsa and firewire jack backends.
So I give a try on 2 others hardware and no matter what I do dropouts
are always here ...
I think your case was different since I have no crash like " zombified -
calling shutdown handler " but "only" watchdog: signaling pd... and
dropouts.
And troubles arises only when the -rt patch is started with -nogui.
Very simple patch like just [osc~] and [dac~] doesnt' trigger the
watchdog.
