Well, I am not sure if you would like the experience with the R390X. My cards
before this one were a HD6950 and before that a HD5750 and I have to admit that
I liked the prec-GCN experience a lot more - those hard lockups are really ugly
and frustrating at the moment, I am happy that at least Compiz runs as expected
so I can use my desktop normally... but it seems almost all other OpenGL
applications I've tried seem to have major problems with the radeonsi/R390X
combi.

No need for any apologies, I appreciate any help I can get.
And no, I did not know about the Magic SysRq key magic - very useful - I will
try that next time:
 "Raising Elephants Is So Utterly Boring" or "Reboot Even If System Utterly
Broken" magic, haha.

Great tip, thanks a lot.
