--- Comment #3 from David Smith <dsmith at redhat dot com> ---
I'd certainly suspect utrace, especially since I see utrace_free() in your
dmesg output. However, I also see _raw_spin_lock, and that's got me confused.
We added some patches recently to add support for realtime kernels, but we
shouldn't be using raw spinlocks anywhere but realtime kernels.

The only real utrace change lately was the following:

commit d9d07e99777c6e7aaaa8db0049c5fd5e5a2f01b0

    Fixed PR17181 by making utrace handle interrupting processes better.
