Still no error message in the Xorg log, which means this *isn't* bug 120834 (which always logs Error in I830WaitLpRing()), and could be something that freezes the system so completely that it can't log anything. I suggest the following:
-Reproduce the crash -Try Ctrl+Alt+F1 (should switch to a text mode terminal) and Ctrl+Alt+Backspace (should restart X) -If nothing happens, hold down Alt and SysRq(PrntScrn) and press 1, t, e, s, u, i, b in that order, allowing any disk activity to finish between each (the first two log a call trace, the rest shut down and reboot the system as gracefully as possible) -Post /var/log/syslog, and which of the above worked -- blender causes hard freeze https://bugs.launchpad.net/bugs/177518 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
