This might be a kernel related bug and I believe it might be related to some of the other bugs in launchpad filed against the ati driver even though it's probably a kernel bug. On my mobility x300 in jaunty googleearth, glxgears and warcraft 3 + 6.59 + AI dota map under wine would always crash the system. Also randomly Xserver would crash (screen goes blank or sometimes corruption and looks like screen rolls down in a circular motion a few times before X crash and we're dumped into gdm again) - but doesn't hang system. Happens with or without compiz. Certain types of crashes that I can trigger responds to magic sysrq reboots, sometimes does not.
The bug seems to have been introduced to the kernel after alpha6 since some people reported it came into effect after the beta (I only started using during beta so have always experienced it), and fixed in 2.6.29.1 though unclear whether it was reintroduced in the 2.6.30-rc's. Cross distribution issue too it seems. After following the discussions on various bug reports and phoronix forums(see http://www.phoronix.com/forums/showthread.php?s=7b34fbce557a386b5b3c499e5b811b8f&t=14424&page=7), I see that after upgrading to the 2.6.29.1 ppa mainline kernel (http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29.1) the random crashes for everything I described above APPEARS to have disappeared(have not experienced a crash since - now for more than a day). I am no kernel developer so have no clue what got patched to fix the issue. There seems to be a small graphics performance hit in this version but at least no crash. There is supposively a workaround for the .28 kernel by turning things like apic and acpi off during boot - I have not tried so can't confirm. Someone reported somewhere that the .30-rc3 kernel regresses and reintroduces the bug, but I cannot find that forum thread and have not personally tried, so am unable to confirm those allegations. I hope this alleviates the suffering for some of you. -- Crashes using glxgears / googleearth on x1400 https://bugs.launchpad.net/bugs/363678 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
