I removed the global env R600_DEBUG=nodma before this test, didn't seem 
to matter anyway...

dolphin has pid 560:

$ grep radeonsi /proc/560/maps
7f7e70906000-7f7e7100a000 r-xp 00000000 00:0e 2125313                    
/usr/lib64/mesa/radeonsi_dri.so
7f7e7100a000-7f7e71043000 rw-p 00703000 00:0e 2125313                    
/usr/lib64/mesa/radeonsi_dri.so

So that's something, I guess...

So, newly compiled mesa from git with assertions/debug enabled:

(... repeating a few times, guessing there's missing icons in the 
themeset or something. dolphin itself does not crash...)
