Comment # 14 on bug 76475 from Ilia Mirkin

Erm oops. I guess 'w' is not what I wanted (perhaps because the tasks aren't
actually blocked). From powertop, seems like it's from
nouveau_connector_hotplug_work which is probably triggering more work for
itself :(

That's a separate bug though. While I'm fairly sure I've seen this before, I
don't see a bug open about it. Could you open a fresh one, and include a boot
log with the following module settings (e.g. passed in via kernel cmdline)

nouveau.debug=debug drm.debug=0xe

I'm guessing this will keep generating oodles of output, I don't need the
infinite log, but a good chunk that includes a bunch of the repeats would be
great.
