Since upgrade to 2.6.38.2 i see this messages in dmesg very often - but did not find any other visible error i can tell:

They mean that some rendering operations are dropped, do you notice any visual elements missing or looking incorrect? Is there anything related in the stderr output of 3D apps?
Please attach (as opposed to paste) the output of glxinfo.

GlxInfo Output. Sometimes i miss the graphics of my gnome cpufreq applets (got 4 - 2 are showing, 2 are garbled - don't know if this is related to those error messages).

It might be. If you disable/remove the garbled ones, do the kernel messages stop?
Are you using compiz or another compositing manager that uses OpenGL?

--- Comment #4 from Torsten Krah tkrah@fachschaft.imn.htwk-leipzig.de 2011-04-06 06:04:23 PDT --- At the moment all are showing fine and nothing is garbled - no kernel messages shown at the moment (don't know how to trigger them). No i am using plain metacity - all effects disabled, no OpenGL usage afaik.

--- Comment #5 from Michel Dänzer michel@daenzer.net 2011-04-06 06:57:12 PDT --- If there's no OpenGL involved, it can't be a Mesa driver issue. So you're saying that the messages happened while only using the X driver, and only with kernel 2.6.38.2? Which kernel did you use before?
