--- Comment #10 from MC Return mc.return@gmx.net ---
Oh, Ok, Not that I have the same card anyway, but I can't test Tropics as I am on a pure 64bit setup.
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.
WRT the hard lock did you try SysRq? Apologies if you already know all this -
Press and hold both <Alt> and <SysRq> keys, while still holding them press and release <s> wait a sec, then press and release <u> then <b>. If it works then this is a cleaner way than a hard reset as the <s> syncs disks and the <u> remounts them read only then hopefully the <b> reboots.
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.
