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.
