[Bug 91880] Radeonsi on Grenada cards (r9 390) exceptionally unstable and poorly performing

It's supported. Please attach your xorg log, dmesg output and a copy of your vbios. To get a copy of your vbios: (as root) (use lspci to get the bus id) cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/vbios.rom echo 0 > rom

Thanks for responding. I added the log and the ROM. Still, even on the newest Linux from Git I get a display crash/hang whithout disabling DPM in Kernel line, so I'm not sure if I can supply an Xorg log with DPM switched on. Performance on this freshly built kernel (without DPM) is still the same as before: somewhat low.
