--- Comment #54 from dwk128 at gmail.com ---
Unfortunately, while this patch (against drm-nightly 4.6.0-rc5) did eliminate
the stack traces from my dmesg logs, it seems to have *introduced* a freezing
bug. Every six to twelve hours or so the system freezes completely, audio
stops, caps lock stops working (though it doesn't blink as in a panic). I
assume this is a deadlock of some sort because there is no indication in any
system logs that a freeze has occurred.

I have been having many issues related to suspend, so I thought at first this
freeze was another manifestation of the same bug. But after happening four or
five times, it just happened last night after several hours of being on without
ever having been suspended. I can try the same kernel unpatched but I have
tried a similar version before and I suspect the freeze is new.
