There seems to be no solution. I tried several params, combinations of various
things (some even led to quite serious file system corruption) but it had no
positive effect whatsoever. Playing with powerplay/dpm etc. just made my laptop
overheat a lot.
I had some luck with amdgpu-pro in 2016, but it was even less usable. It always
booted successfully but there was mostly pinkish garbage on the screen (±75%)
although I could see the desktop at some places (±25%) and therefore somewhat
use it (login and reboot). Not sure if it is better nowadays, I think it's
worth a try.
Since this issue is here at least since 4.4 I highly doubt 4.14 or 4.15 will
bring the solution.</pre>
