I didn't fill myself any new issue about this. I only joined discussion which
already started here and on previous related bugreport. Also I have PSR in
working state for more than a year with dirtyfix I created myself. Meanwhile I
provided all information I can everytime one of developers asked. I recompiled
my kernel with every patch that was proposed, tested it and posted logs.

The problem is that I didn't submit those two bugreports myself and they
weren't very clear in my opinion. I tried bring some new information but it was
probably lost in translation. I think PSR was enabled in every log I posted. I
wrote explicitly about PSR in
https://bugs.freedesktop.org/show_bug.cgi?id=97918#c22 in February. Honestly I
thought that devs knew this issue is strictly connected to PSR.

Also that was You who insisted on merging wrong solution
https://bugs.freedesktop.org/show_bug.cgi?id=101111#c5 . My first post in this
topic is after that comment of yours.

I agree with you but I hope you reconsider my role after reading my
explanations above. I believe everything is clear now. Many thanks for you and
all the rest of the devs who helped.
