I tried to work around the problem using a 2.6.29 kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.6/
At least using the specific version 2.6.29-02062906 the bug did NOT disappear! Maybe they are less frequent but for me it is not solved using that kernel. Again I retrieved a backtrace via gdb. Looks quite similar to me. ** Attachment added: "gdb-07-04.txt" http://launchpadlibrarian.net/28685517/gdb-07-04.txt -- [RV250] Kubuntu: X Freezes with Radeon driver EXA/XAA Composite https://bugs.launchpad.net/bugs/348332 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
