Summary: X crashes when simultaneous rendering is triggered Product: xorg Version: 7.2 Platform: x86 (IA32) URL: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg- video-ati/+bug/118798 OS/Version: Linux (All) Status: NEW Severity: normal Priority: medium Component: Driver/Radeon AssignedTo: xorg-driver-ati@lists.x.org ReportedBy: [EMAIL PROTECTED] QAContact: [EMAIL PROTECTED] This is also reported at Launchpad: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/118798 I've reproduced this user's crash on an M24 radeon mobility x600. I wasn't able to reproduce it on a Mobility M7, nor on an RV280. "I have a reproducible X crash when using a simple python program. This code uses the VTK library (package python-vtk). I will attach the code in a reply Procedure : the program creates 3 rendering windows. In the beginning of the program, all the three windows are stacked on top of each other. three steps are necessary : - Move one of the windows besides the two others - Pick one of the remaining stacked windows and move it so that it covers (at least partially) the other two windows. - Move again this same window to uncover parts of the other two windows. This will trigger rendering of these windows, and X crashes... the interesting part of DMESG is : [ 148.253647] allocation failed: out of vmalloc space - use vmalloc=<size> to increase size.
