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:

CC Steven, as the bug shows up when testing the trace events, and it's related to printk (un)buffering :)

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 <[email protected]>
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:

[    1.665656] WARNING: at /c/wfg/linux/kernel/rcutiny.c:67 rcu_idle_enter_common+0x103/0x1b2()

Hi Paul,
Fortunately this bug is bisectable and the first bad commit is:
commit 9b2e4f1880b789be1f24f9684f7a54b90310b5c0
Author: Paul E. McKenney <[email protected]>

rcu: Track idleness independent of idle tasks

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().

Hi Paul,
Fortunately this bug is bisectable and the first bad commit is:
commit 9b2e4f1880b789be1f24f9684f7a54b90310b5c0

rcu: Track idleness independent of idle tasks

Quoted 8 lines

Quoted 6 lines
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?
Not exactly, but the error message is now changed to:

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?

And finally I tried the patch on top of rcu/next, and get the attached dmesg and warnings:

rcu: Track idleness independent of idle tasks
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?

This one failed in my testing. Please see the end for the fixed version, with on small but important change.

Thanx, Paul

Not exactly, but the error message is now changed to:

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.

Both trees freeze after this point:

And that's bisected to Al's vfs work..

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

And finally I tried the patch on top of rcu/next, and get the attached dmesg and warnings:

That's a great kconfig (from the testing respective)! :-P

Could you please try replacing my earlier patch with this one?

Thanx, Paul

Hi Paul,
Fortunately this bug is bisectable and the first bad commit is:
commit 9b2e4f1880b789be1f24f9684f7a54b90310b5c0
Author: Paul E. McKenney <[email protected]>

rcu: Track idleness independent of idle tasks
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?
This one failed in my testing. Please see the end for the fixed version, with on small but important change.
It worked, thanks!
Tested-by Fengguang Wu <[email protected]>

Very good! (And please ignore my resend of the same patch.)

I will queue this.

Thanx, Paul

Will you recommend it for -stable? It impacts 3.3/3.4. I tested it on 3.4 and it works fine. However for 3.3, the patch cannot apply cleanly.

Thanks,

If someone hits it in a real workload, I might consider it. I currently have it queued for 3.7.
