Bug ID: 93001 Summary: modprobe radeon dpm=0 and starting Xorg sometimes logs "general protection fault" and no output Product: Drivers Version: 2.5 Kernel Version: 3.18.6 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: jackfritt@boh.de Regression: No

I need to blacklist the radeon module in debian. Loading of radeon only works with modprobe radeon dpm=0 on the console, autoloading with kernel command line will crash kernel and needs powercycle. I have to power on my Monitor before kernel load, not module load! If i try to power on my Monitor after kernel load, I never get an output. Even when I try to load radeon module.

I have the problems since 3.18, before this I used 3.12 kernels without these Problems.

Can I give more info?
