If you also have an X220, this seems like I have an hardware issue. As there are new kernels every week and I boot my machine once a day, the chance of booting with a new kernel is not that small. In the UEFI I noticed that I cannot save anything any more. Therefore I fear that the UEFI chip has some sort of hardware malfunction. A UEFI upgrade did not really change anything. Screenshots are a little down in the question: http://unix.stackexchange.com/q/271045 What kind of CPU do you have in your X220? I have the Intel Core i5-2520M. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
