Hi Paul,
I kicked off boot testing for dozens of randconfigs and got some few
runtime errors. Here is one of them. It's very reproducible in kvm,
and obviously only triggers on the attached config.

And I find the somehow disordered output (the timestamp at the end of
line and the blank line etc.) is indeed a very stable pattern. For
example, here is another trace:

Hi Paul,
Fortunately this bug is bisectable and the first bad commit is:
commit 9b2e4f1880b789be1f24f9684f7a54b90310b5c0
Author: Paul E. McKenney <paul.mckenney@linaro.org>
Date: Fri Sep 30 12:10:22 2011 -0700
rcu: Track idleness independent of idle tasks
However, at that commit, the error messages are a bit different:

OK, there is a problem in TINY_RCU's handling of dyntick-idle: it
traces while in idle. The confusion on my part was that in TREE_RCU,
the nesting and dyntick-idle indication are different, while in
TINY_RCU they are one and the same.
Does the following patch help?
Thanx, Paul
------------------------------------------------------------------------
rcu: Pull TINY_RCU dyntick-idle tracing into non-idle region
Because TINY_RCU's idle detection keys directly off of the nesting
level, rather than from a separate variable as in TREE_RCU, the
TINY_RCU dyntick-idle tracing on transition to idle must happen
before the change to the nesting level. This commit therefore makes
this change by passing the desired new value (rather than the old value)
of the nesting level in to rcu_idle_enter_common().

Then I think it may help to test the linux-next tree that contains
latest RCU fixes. And it somehow helped. There are no warnings in
the linux-next tree 1 or 2 days ago; there is a maybe unrelated warning
in today's linux-next tree.

So I'd better to base the test on one of your RCU branches..
Which branch would your recommend?

That's bisected to one of Tejun's workqueue commit..

rcu: Pull TINY_RCU dyntick-idle tracing into non-idle region
Because TINY_RCU's idle detection keys directly off of the nesting
level, rather than from a separate variable as in TREE_RCU, the
TINY_RCU dyntick-idle tracing on transition to idle must happen
before the change to the nesting level. This commit therefore makes
this change by passing the desired new value (rather than the old value)
of the nesting level in to rcu_idle_enter_common().

rcu: Pull TINY_RCU dyntick-idle tracing into non-idle region
Because TINY_RCU's idle detection keys directly off of the nesting
level, rather than from a separate variable as in TREE_RCU, the
TINY_RCU dyntick-idle tracing on transition to idle must happen
before the change to the nesting level. This commit therefore makes
this change by passing the desired new value (rather than the old value)
of the nesting level in to rcu_idle_enter_common().

If someone hits it in a real workload, I might consider it. I currently
