Subject: um: rcu_sched_state detected stall on CPU 0

Hi,

I'm seeing often messages like this one on my UML:
...
INFO: rcu_sched_state detected stall on CPU 0 (t=7348 jiffies)
...

The system often seems to be frozen.
When I press a button it wakes up immediately and continues to run.

Any ideas?
Config is attached.

Cheers,
