The Saucy kernel in -proposed has now been rebased to upstream 3.11.2. If this is fixed upstream, the fix should have made it's way in to the Saucy kernel with this rebase. Can you test the latest -proposed kernel to see if it resolves this bug:
https://launchpad.net/ubuntu/+source/linux/3.11.0-9.16/+build/5055306 Both the linux-image and linux-image-extra .deb packages need to be installed from that page. Another option would be to just enable the -proposed repository: https://wiki.ubuntu.com/Testing/EnableProposed ** Also affects: linux (Ubuntu Saucy) Importance: High Status: Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1227023 Title: Machine locks up a few times a day Status in “linux” package in Ubuntu: Confirmed Status in “linux” source package in Saucy: Confirmed Bug description: My machine is locking up a few times a day. These lockups seem to be graphics-related -- they often occur when opening a new tab in Chromium or a new window or Unity indicator menu shows on the screen -- but are not universally so. Sometimes the machine will lock up of its own accord when no-one is using it at all. When locked up, the machine is unresponsive to keypresses and mouse movements; I cannot, for example, switch to a virtual console. It will not answer ssh connections (the network going down is why I think it might be a kernel problem rather than X). It *does* respond to SysRq+REISUB. However, SysRq+1t does not leave any trace in kern.log after a reboot. I have run memtest86 overnight and it shows no errors. This started happening under raring; I have upgraded to saucy in the hope that it would fix the problem and it has not. It occurs using both Xorg and Xmir. I am unable to trigger the problem at will.
