please attach your xorg log and dmesg output. Created attachment 45568 [details]
Xorg log file.
Created attachment 45569 [details] [review] dmesg output. Hope this helps! Found out something interesting: Even without xf86-video-ati and ati-dri installed I get the same corruption with the proprietary catalyst when starting Archlinux without 'nomodeset' kernel parameter. Tried xorg 1.8 and 1.9 - still the same corruption. I'm deadly sure that the driver worked fine back in September 2010. Okay, this seems to be a kernel issue? I have no problems at all with kernel versions =< 2.6.37-5 . What kernels are problematic? Can you bisect? (In reply to comment #7) > What kernels are problematic? Can you bisect? 2.6.37-5 with Arch patchset works fine, the problem is present with 2.6.37.5-1-ARCH and all the 2.6.38 kernels from Arch repository (including the latest one 2.6.38.2-1-ARCH). The default Ubuntu Natty kernel currently shipping with the Live CD daily builds is also problematic (2.6.38.8.22) (In reply to comment #8) > (In reply to comment #7) > > What kernels are problematic?

Assuming 2.6.37-5 with Arch patchset and 2.6.37.5-1-ARCH are fairly close, can you track down the problematic change? If not, bisecting a vanilla kernel would be helpful. Ok, v2.6.37.1 vanilla seems to be good and with v2.6.37.2 vanilla corruption is present. I will bisect as soon as possible.

[94a99842f0e2738d338e5256a7cca4b8e30adf94] drm/radeon/kms: hopefully fix pll issues for real (v3) This seems to cause the corruption. Created attachment 45820 [details] [review] possible fix Does this patch fix the issue? Yes, it does. Thank you! I've sent the patch to Dave. thanks for testing! |
