Public bug reported: After the update to kernel Linux 3.13.0-149 generic Ubuntu 14.4 crashes after a period of keyboard inactivity . The period is about 1 hour .The crash takes one to a terminal type screen which gives some kernel panic information . At this point the PC has to be physically switched off and restarted. Ubuntu 14.4 crashes on all subsequent Kernel updates upto and including 3.13.0-168 . I now think the crash is connected with the power setting on the PC - 'Power .Suspend when inactive for : nn minutes/hours '. On 3.13.0-168 when the power setting are ' do not suspend' Ubuntu does not crash . I have not tested this on earlier kernels.
