--- Comment #9 from Maarten Lankhorst <bugs at mblankhorst.nl> ---
I would say the kinject is the real root cause here. It injects idle time
because your system is overheating, and atomic updates are really time
sensitive. If we throttle during atomic updates then we won't finish in time
and you get the failure.

Marking not our bug, because it probably isn't. :)
