[Bug 111805] Constant "Resetting rcs0 for hang on rcs0" and machine lockup

--- Comment #35 from Kenneth C <kenny at panix.com> ---
Since Chris W has fixed an issue with the drm-tip I'd had with increased
current draw when in S0 (see
https://bugs.freedesktop.org/show_bug.cgi?id=111909) in commit c601cb2135, I'd
decided to try drm-tip again.

So last night, I took the drm-tip as of 9d229bec4f5, merged Linus' tip with
that, and have been running with an external monitor and running continuous
videos for hours now, and have run several suspend cycles (which seems to have
exacerbated this issue).

I'm glad to say I haven't seen a hiccup in over 15 hours and only a couple of 
"Atomic update failure" and "Failed to enable link training" messages in dmesg
(which appear to be normal, but I can post them if needed).

So to make sure, apparently the best way to get something to break is to
publicly announce it "fixed", so here I go: I think this is now fixed in the
drm-tip.

... fingers crossed
