Comment 135 for bug 311895

It wasn't the only patch, I also applied the tiny patch from bug 20520 (register restoring ordering fix for resuming). However, I tested that patch in isolation before, and it worked fine. Also, I don't think that code path is active on boot. There was no other kernel update.

I'll send detailled debugging information tomorrow (I hope I can ssh into the machine still, or it gets logged far enough), bed time for today. I just wanted to give you an early warning to perhaps defer propagation of the patch (or just revert it for now, since it just works without it.
