It looks like the system isn't letting the rcu_sched grace-period kthread
run:
[402138.240512] rcu_sched kthread starved for 2757 jiffies! g53669 c53668 f0x0
RCU_GP_WAIT_FQS(3) ->state=0x1
This kthread tried to wait for a few jiffies (the exact number depends
on HZ and the number of CPUs), but 2,757 jiffies have elapsed and it is
still waiting. This kthread is responsible for detecting idle CPUs and
reporting quiescent states on their behalf, so if this kthread doesn't
get a chance to run, then the stall warnings you are seeing are expected
behavior.
I am seeing someething like sort of like this in my rcutorture runs,
but only when I boot with nr_cpus quite a bit bigger than maxcpus, as in
something like nr_cpus=43 and maxcpus=8. This causes 8 CPUs to be brought
online at the usual time, and the other 35 come online some time later.
One difference from your situation is that I see the grace-period
kthread in ->state=0x401 (TASK_WAKING) instead of your ->state=0x1.
If I send extra wakeups to the grace-period kthread (which shouldn't be
needed), it does make progress, but then other kthreads fall into that
same half-woken state.
So now that I ahve shared the full extent of my ignorance on this topic,
any ideas? ;-)
Thanx, Paul
