This problem happens constantly for me. Seems to most often coincide with swithing my kvm over (so usb connect) or using the wheel on my logitech mouse.
Same symptoms: ATI graphics card xorg process shows 100% cpu UI freezes Only a reboot clears it up. ** Attachment added: "apport.xorg.izJ4ZJ.apport" https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/881526/+attachment/2728408/+files/apport.xorg.izJ4ZJ.apport -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to fglrx-installer in Ubuntu. https://bugs.launchpad.net/bugs/881526 Title: System freezes, kernel crashes, "[fglrx] ASIC hang happened" To manage notifications about this bug go to: https://bugs.launchpad.net/fglrx/+bug/881526/+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
