Comment 31 for bug 1449401

Hi Timo,
> No need to test further mainlines, the backports that work fine on trusty kernel somehow broke here.
I have the same problem (blank screen when booting my broadwell-based thinkpad) under trusty. My current work-around is to use the previous kernel 3.16.0-34, or, to boot with -36 in recovery mode and then choose 'resume normal boot' (which then goes through fine). Could it be that the backport is broken there too? Or is that a separate bug report?
Thanks,
Philipp
