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.
