Summary: radeon driver on HD6570 shows pixel noise Product: Drivers Version: 2.5 Kernel Version: 3.* 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: ccvs@mail.ru Regression: No
Videocard HD6570.
when I call "modprobe radeon", I see pixel noise on the screen and, if try more, it's possible to see some characters from framebuffer console.
dmesg shows, that firmware loads right
without firmware module loads, but it's useless, besause X driver needs KMS, which is disabled without firmware

--- Comment #7 from Vladislav Tcendrovskii ccvs@mail.ru 2012-05-24 16:30:46 --- I have tested kernel 3.4.
Results look a bit strange:
When i use modprobe radeon, I have the same pixel noise, which I had before.
If I start X, I have screen with windows and noise.
When I return to console, noise disappers.
If I return to X, it also works fine.

--- Comment #9 from Vladislav Tcendrovskii ccvs@mail.ru 2012-05-25 20:10:06 --- I've tried this patch on kernel 3.4, but the only visible result - switching from noisy X screen to framebuffer console is much faster.
After such switching noise disappears.
