--- Comment #22 from MirceaKitsune <sonichedgehog_hyperblast00 at yahoo.com> ---
Wasn't sure whether to bump this same bug report, as the original issue has
clearly been fixed during nearly an year of countless Kernel + Mesa + driver
updates. Unfortunately I now experience a new issue acting just like what I
described here at the time: When certain 3D engines are running, there is a
chance that after a few minutes the machine instantly freezes and becomes fully
unusable until powered off and back on. I don't know when the new crash was
implemented since I haven't played a lot of 3D games recently, but I'd assume
somewhere within the last few months.

I now have Kernel 4.15.3 and Mesa 18.0.0. Again my video card is a Radeon R7
370 from Gigabyte (RadeonSI, GCN 1.0, AMD Pitcairn Islands). I'm running the
openSUSE Tumbleweed x64 rolling release distribution.

Can someone please explain a way to debug those instant system freezes as
they're added to the system components? I can't get an output at the time of
the crash as the entire machine stops working and becomes bricked until
restarted (likely including SSH), but maybe I can make it log info that I can
retrieve after I reboot? Any useful info will help, just please nothing
dangerous that might permanently break my OS.
