If so, it should be fixed with these patches: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9babd35ad72af631547c7ca294bc2e931cc40e58 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7848865914c6a63ead674f0f5604b77df7d3874f Alex Greetings Alex, it work with radeon.runpm=0, I'll test the patches now and report back. combination of both patches (the first was existing already in 3,13,6) the gpus are working again. Thanks!
