Summary: [radeon cayman regresion] artefacts on screen Product: Drivers Version: 2.5 Kernel Version: 3.0.0-rc3 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: kernellist@neutrinus.com Regression: Yes
When running kernel versions => 3.0.0-rc3 there are a lot of artifacts on screen when runing xorg.
Kernel 3.0.0-rc2 and olders were producing clean image, right now there are artifacts on screen, making any fonts/graphics unreadable. 3.0.0-rc[3-5] are affected. It fully reproducible: just run kde :) Its happends everytime when I switch 3.0.0-rc2 kernel to something newer.
I'm using debian AMD64 sid+experimental, kernel images from experimental. I'm using xorg "radeon" driver. Mesa: 7.11~0-2.
There are no Ops, no strange logs in dmesg...
