Summary: Radeon DRM with 2x ATI 4850 linked in Crossfire-X
leads to blank screen with modeset=1
Product: Drivers
Version: 2.5
Kernel Version: 2.6.34
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Video(DRI - non Intel)
AssignedTo: drivers_video-...@kernel-bugs.osdl.org
ReportedBy: adrien.dessem...@gmail.com
