Jan, I am closing this bug since the original reported problem does not happen anymore according to what you said.
Please open a new bug report if the hardlock problem persists with the latest packages. We'd appreciate it if you try the latest packages in Edgy Knot 3 to test the hardware. Thank you for reporting this bug and being prompt with the feedback :) ** Changed in: xserver-xgl (Ubuntu) Status: Needs Info => Rejected -- xserver-xgl: fails on amd64 with opensource radeon-dri drivers https://launchpad.net/bugs/26484 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
