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.

What kind of CPU do you have in your X220? I have the Intel Core i5-2520M.
