Hardware x86-64 (AMD64)
OS Linux (All)
Status NEW
Severity normal

Component DRM/Radeon

Hello there, I'd like to report that since kernel 3.15 its nearly impossible to
boot past the grub screen because post grub, during X init my monitor starts to
endlessly power down/ power on. The only way to boot is to play around with the
restart button, in arround 10 restarts, ~once I would get X to initialize
properly. The other way is to put radeon.dpm=0 in the kernel-line. This way no
errors occur, but I am left without dynamic power managemenent for the GPU.
