After an hour or so (maybe less) I'm getting /var/log/kdm.log full of errors: CS section size missmatch start at (../../src/radeon_textured_videofuncs.c,R300PrepareTexturedVideoCP,2184) 66 vs 62 CS section end at (../../src/radeon_textured_videofuncs.c,R300PrepareTexturedVideoCP,2418)

and Xorg process CPU usage gets to near 100% even or P4 with HT so KDE desktop gets almost unresponsible (wating for few seconds for almost every operation).

At system boot everything is OK - Xorg CPU usage for few percent sometimes even less, kdm.log doesn't have such errors but after some time using KDE desktop (no matter if there are KWin effects or not) the problem as described above occurs.

The problem occurs from at least commits from 2010-10-27 (I'm testing r300g from xorg-edgers/radeon ppa). I haven't noticed this problem before but before that date I've used Kubuntu 10.10 + r300g from xorg-edgers/radeon ppa booted only from pendrive for hour, maybe sometimes some more time between reboots and now I use the same configuration installed on hard disk.
