Bug#815173: kernel-image-4.4.0-1-amd64 does not boot on my Thinkpad X240
Package: linux-source-4.4
Version: 4.4.2-2
Followup-For: Bug #815173
Dear Maintainer,
I have the same problem on my MS Surface Pro 4. However, I was able to
tickle out the problem by booting with 'earlyprintk=efi,keep' appended to
my kernel parameters.
My problem is an unhandled kernel paging request in efi_bgrt_init(). I
dug around and found the following fix that works for me:
[PATCH] x86/efi-bgrt: Fix kernel panic when mapping BGRT data
https://lkml.org/lkml/2015/12/10/599
The problem might be different for the Thinkpad reports here, however maybe
the earlyprintk will help get to the root of the problem.
Regards
