Summary: Kernel Mode Setting Fails on Radeon X700
Product: Drivers
Version: 2.5
Kernel Version: 2.6.35.5 x86_64
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
AssignedTo: drivers_video-...@kernel-bugs.osdl.org
ReportedBy: kager...@gmail.com
Regression: No

Full 'lspci' Output
The kernel fails to set any video mode when booting, reverting automatically to
a standard VGA console. X.org does not succeed at initializing video with the
radeon driver either, so this issue is not limited to the kernel DRI.
When testing with amd64 kernel at
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35.5-maverick/ :
