On my Lenovo ThinkPad T61, I tried kernel 3.14.1-031401-generic, but at boot it fails. It shows me a panel stating I have problem with the display and input devices. I then press "enter" and another panel with 4 options shows up, including going into low graphic mode. At this point, the mousepad does not work and the panel does not accept my keyboard input anymore. I can switch to one of the consoles with CTRL- ALT-F3 and there, my keyboard does work.
I am running the Nvidia proprietary driver but I really need it. Since this bug comes occasionally, say once every 2 months, there is no point for me using the open source drivers as they would render my laptop useless for my work. If that is the problem causing 3.14.1 to fail. then running a mainline kernel is not an option for me. -- 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/1301003 Title: kworker runs with 40-60% CPU because of modules e1000 and/or e1000e Status in “linux” package in Ubuntu: Incomplete Bug description: Once in a blue moon, lets say once every two months, kworker runs with 40-60% CPU because of kernel modules e1000 and/or e1000e. Reboot the machine does not help. I rebooted twice to no avail I then ran: sudo modprobe -r e1000 sudo modprobe -r e1000e and the problem was gone. When I run the following afterwards: sudo modprobe e1000 sudo modprobe e1000e ... the kworker ran for less than 1s and exited. This particular problem was already reported in bug #887739. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/887793 but was not the problem of the person that reported it, thus this new bug report.
