Bug 1056511 has a proposed fix posted to it; if you suspect this might be a dupe of that bug then it would be worthwhile to test that patch.
Bug 1053702 (and bug 1045845) is another recent cirrus crash that was fixed about a month ago. If you've not reproduced the crash in October it is possible that was the cause of the problems. In either case, please set this as a dupe accordingly. If the crash still occurs with latest quantal please post a fresh backtrace - see http://wiki.ubuntu.com/X/Backtracing for guidance. ** Changed in: xserver-xorg-video-cirrus (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-cirrus in Ubuntu. https://bugs.launchpad.net/bugs/1043513 Title: Xorg crashed with SIGABRT in memcpy() via cirRefreshArea() under KVM virtual machine To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-cirrus/+bug/1043513/+subscriptions _______________________________________________ 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
