Priority: medium Bug ID: 76490 Assignee: dri-devel@lists.freedesktop.org Summary: No output after radeon module is loaded (R9 270X) Severity: normal Classification: Unclassified OS: All Reporter: mail@geleia.net Hardware: Other Status: NEW Version: unspecified Component: DRM/Radeon Product: DRI
Created attachment 96217 --> https://bugs.freedesktop.org/attachment.cgi?id=96217&action=edit kernel log
The screen goes black after the radeon module is loaded. The only way I can get any output is to blacklist the radeon module, load it via modprobe and then change the resolution with xrandr from another computer via ssh.
I seem to get some sort of lockup if I don't blacklist the module, because then I get a black screen at startup and I cannot even ssh into the machine. I tried to enable netconsole from the kernel command line but I can't get it to work (do I have to compile it statically?).
I tried this with 3.14-rc6. For reference, I'm including the log output I get after I load the radeon module.
This card is an MSI R9 270X Gaming 4G.
