--- Comment #7 from Gustavo Lopes mail@geleia.net --- I installed it now, but still no luck.
glopes ~ $ ls -l /lib/firmware/radeon/PITCAIRN_mc* -rw-r--r-- 1 root root 31100 Mai 13 18:58 /lib/firmware/radeon/PITCAIRN_mc2.bin -rw-r--r-- 1 root root 31076 Mar 23 02:02 /lib/firmware/radeon/PITCAIRN_mc.bin
When I run with radeon.dpm=0, it seems to load the correct file:
[ 0.630585] [drm] radeon: 4096M of VRAM memory ready [ 0.630586] [drm] radeon: 1024M of GTT memory ready. [ 0.630593] [drm] Loading PITCAIRN Microcode [ 0.630632] [drm] radeon/PITCAIRN_mc2.bin: 31100 bytes [ 0.630644] [drm] Internal thermal controller with fan control [ 0.630673] [drm] radeon: power management initialized
I'm attaching the full log as well.
