Can you bisect?
Hello Alex,
I'll try 'cause I get the same with clean 3.12-rc2 + 0001-drm-radeon-avoid-UVD-corruption-on-AGP-cards-using-G.patch
radeon.agpmode=8 works as before, but radeon.agpmode=-1 gave
[-] [ 10.958649] radeon: `-1' invalid for parameter `agpmode' [ 11.515274] radeon: `-1' invalid for parameter `agpmode' FATAL: Error inserting radeon (/lib/modules/3.12.0-rc2-1-desktop/kernel/drivers/gpu/drm/radeon/radeon.ko): Invalid argument
We haven't touched anything AGP related in radeon in years.
I know. ;-)
Maybe some general kernel module parsing change?
That was my thought, too.
Any point to start without git-tree?
You really need a git tree to bisect.
I know, second time, but... ...I'll see what I can find in Linus 3.12-rc1 (maybe before) patch file(s) (logs). For several git trees this system is to small...
