Subject: kernel 3.1 lots of cpu stalls and lockups

Hi,
since updating from kernel 3.0 to 3.1 I'm experiencing lockups.
They happen quite randomly, sometimes after 1 day of running,
other times after few hours or just few minutes after booting.
I don't have an idea what may be causing them, but in dmesg I see lots of
INFO: rcu_preempt_state detected stalls on CPUs/tasks: {} (detected by
0, t=18002 jiffies)
and backtraces.
Please have a look at following ArchLinux bug report with logs and comments from
other affected people.
