Ethernet controller: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01)
Network adaptor seems to play a role with this bug. Without the network controller activated my system seems stable, but as soon as a switch on my network my system reacts differently: when starting Firefox my mouse pointer freezes a couple of seconds, but it doesn't when my network controller is switched off. Screen flashes sometimes (with network off screen is normal) etc. Seems that the Atheros driver somehow interferes with Xorg and/or Compiz. Do others also have atheros network adaptors? Can you also try to disable your Atheros card? I have somewhere a USB network adaptor, but can't find it. As soon as I find it, I will try if my system is stable with this network adaptor. Hope this will help find a solution. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/993187 Title: ubuntu 12.04 64bit completely freezes frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/993187/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
