<pre>R9 390 owner here. Just replaced my old Ubuntu 14.04 + fglrx with Fedora 25,
then 26 + Mesa and hit this problem as well. It took me a lot of fiddling and
searching to understand why my 3 years newer system has become unusable.
The only thing that worked for me was radeon.dpm=0 but, well, (expletive), my
400€ card has been reduced to a 40€ card thanks to this.
I can report that I tried #115 and it didn't solve it for me. What it did
though, was to delay the crash from 10 seconds to about one 30-60 seconds (I'm
getting a full hard crash with black screen, dead I/O, all fans maxing out,
regardless of what I'm doing, if I'm fast I can get to run Unigine Valley for a
bit, if I don't then it can crash while desktop is sitting idle).
I'm not very Linux-handy, but if anybody needs my system as a guinea pig for
hopefully solving this, please let me know, I'm willing to help.
And if someone has knowledge whether a fix is (still) under work, please update
us here.</pre>
