radeon problems with latest -current update
I updated -current today and have run into a serious problem.
This is KDE: http://68.45.22.62/X-KDE-current.png xfce shows the same basic problem. Upon starting X, dmesg fills with: Code:
[ 205.345807] radeon 0000:07:00.0: r600_cs_track_validate_cb:203 cb pitch (64) invalid Code:
[ 23.351119] [drm] Initialized drm 1.1.0 20060810 Adam |
Strange! Looks like an old libDRM library speak gibberish with the kernel's DRM part!!?!!? Try an rebuild of libdrm and mesa.
|
I did reinstall libdrm and mesa, but not rebuilding from source. Guess I can give that a shot.

I'm running 2.6.36.3 now, built using the config for 2.6.35.10-huge, and now everything is fine. Looks like 2.6.35.10 has a bug in the radeon drm.

If the 2.6.35.10 kernel is broken with the Radeon, I sure hope that the next release of Slackware is delayed until it's fixed. Since the compiler has just been upgraded, why not switch to a more reliable kernel, like 2.6.38 ... ;) Why? I need my Hauppauge remote to work and major new parts of the open source Radeon driver will be included. Personally, I can wait another month or two for a new Slackware release. I actually want a release which works in all respects ... I don't blame Pat and his team, but I AM growing a bit tired of dealing with incomplete and broken kernels... In the meantime, I'll just stick with 2.6.35.7 ....

Of course, it could just be an issue with 2.6.35.10 + HD4850 + my particular motherboard. I'd be interested in knowing if others are having the same problem.

ATI HD4200 motherboard here and I'm not getting those lines in dmesg. The radeon and drm modules are loaded but I have no access to KDE dektop effects at all. It's been like that for a while on -current. I do notice a Xorg.0.log entry calling out libdrm-2.6.0 or newer required. Maybe I'll give that a spin.

Downgrading kernel back to 2.6.35.7 helped. |

My x1600 agp runs acceptably on 2.6.35.7. Braid, Aquaria, WoP ... Yes 2.6.35.10 is broken with radeon. Bug reports abound all over the place. Sadly this was fixed in both 2.6.36 and 2.6.37, but never back ported to the long term supported kernel. Maybe in .11. I've attached the patch from Fedora that fixes this. https://bugzilla.redhat.com/show_bug.cgi?id=664206 IMO, considering you would have to patch .10, and recompile, it might be worth while to just use a working kernel (2.6.35.7), or upgrade and compile a newer non 2.6.35.x series kernel. |
I've stayed on the 2.6.35.7 kernel until 2.6.35.10 gets sorted out.
Here is another report of the same bug: https://bugs.launchpad.net/ubuntu/+s...ux/+bug/703553 Ed |
2.6.35.11 was released with lots of radeon related fixes
