3.14 radeon regression: radeon is broken (pci bug?)
My system works on a 3.13 Fedora kernel. It does not work on a more-or-less identically configured 3.14-rc7+ kernel. The symptom is that the Plymouth password prompt flashes and them the screen goes blank. Hitting escape brings back the text console, and all is well until X tries to start. Then I get a blank screen. killall -9 Xorg from ssh causes these errors to be logged: [ 226.239747] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [ 226.239751] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing CD34 (len 55, WS 0, PS 0) @ 0xCD57 [ 231.241492] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [ 231.241496] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing CD6C (len 62, WS 0, PS 0) @ 0xCD88 [ 236.243111] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [ 236.243115] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing CD6C (len 62, WS 0, PS 0) @ 0xCD88 [ 241.244625] [drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [ 241.244628] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing CD6C (len 62, WS 0, PS 0) @ 0xCD88 lspci -vvvxxxnn on 3.14-rc7+ says: 09:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.
