Thank you very much for backporting the patch!
I have followed the instructions and compiled & installed the patched
kernel. I've been testing the new kernel for two days now and haven't
noticed any screen freezes or seen any GPU HANG errors. Although I think
the patch works perfectly, I was never able to reliably reproduce the
bug (but had multiple GPU HANGs a day). So if you think it needs more
testing than just two days, that's also fine by me.

Cheers,
Tim
