Summary: [KMS] radeon artifacts when switched to graphics after boot Product: Drivers Version: 2.5 Kernel Version: 2.6.38-rc2 (branch airlied/drm-2.6.git/drm-fixes) Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) AssignedTo: drivers_video-dri@kernel-bugs.osdl.org ReportedBy: oldium.pro@seznam.cz Regression: Yes
I have running lines on the screen when the radeon driver takes control (see attached video from system boot). In 2.6.37 it worked fine (some old drm-radeon-testing branch), but in 2.6.38 drm-fixes it started to appear.
I will attach dmesg output for both 2.6.37 and 2.6.38 with drm.debug=3.
