--- Comment #7 from Ruud van Asseldonk <freedesktop at veniogames.com> ---
To summarise: I had i915.enable_psr=1 enabled on 4.4.5-1-ARCH, and that worked
fine. On later kernels this resulted in instabilities, so I disabled PSR. My
system is now stable again, but now I don’t have PSR.

I did not enable PSR to work around another bug, I enabled it to save power.

Using PSR with later kernels is still an issue (or maybe this has been fixed,
frankly I have not tried enabling PSR again after reporting this), but if you
are aware of this and if you have more specific reports for what is happening
there then feel free to close this one.
