@Christopher, sorry this is my main computer, so i cannot re-install
from scratch (also wouldn't really have the time for this and also lack
a separate disk). I assume, just running with old kernels probably
won't work given that they are reasonably old? (otherwise, can you point

to the results?

@Christopher. Sorry, can't answer that question: i never run anything
earlier than quantal on this hardware. On the previous laptop (thinkpad
w500) where i run many earlier versions of ubuntu (including quantal
for a few weeks) i did not notice that problem but then that laptop did
have only 8GB o

I'm already running with the 2.58 ever since i upgraded to 14.04 four
weeks ago. BTW: Given that the problem also appeared on quite different
hardware (bug 1107150) i doubt that it has anything to do with BIOS.
