Are you sure about this bisect results? This changes logic used on gen6+
and shouldn't ever affect your gen3 device. The display corruption is
totally normal for gen3, it usually does that when the gpu hangs. Often a
gpu hang is caused by userspace, are you sure you didn't upgrade anything
else than the kernel?
And we need the full error dump, you cut out the interesting bits ;-)
Thanks, Daniel
