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.

Can you try the following patch against 2.6.38-rc4 or newer and make sure all is working well?

--- Comment #16 from Oldřich Jedlička oldium.pro@seznam.cz 2011-02-11 20:10:45 --- My patch on 2.6.38-rc4 doesn't fix the problem, your patch neither. My patch combined with previous two from mailing list fixes the problem on 2.6.38-rc4.

Can you try this patch? Try uncommenting the following lines to see if either of those flags work any better. Try them individually and together if possible and report back which, if any, helps.
/*pll->flags |= RADEON_PLL_PREFER_MINM_OVER_MAXP;*/
/*if (ASIC_IS_AVIVO(rdev)) pll->flags |= RADEON_PLL_USE_FRAC_FB_DIV;*/

--- Comment #18 from Oldřich Jedlička oldium.pro@seznam.cz 2011-02-12 16:26:09 --- Results with 2.6.38-rc4 and first/second block uncommented (no=commented, yes=uncommented):
first second result ------------------- no no bad (usual) yes no worse no yes good yes yes good
The result is that the second block (RADEON_PLL_USE_FRAC_FB_DIV) has to be uncommented on my system. I've tested only LVDS, not any dual-screen configuration.
