So I can't resume properly from disk too, on the Intel laptop this time. Top
commit is from tip/master:
commit 516f48acf59722429acd323b3d283f74f02891fe (refs/remotes/tip/master)
Merge: a4823bbffc96 dd9506954539
Author: Ingo Molnar <mingo@kernel.org>
Date: Mon Jul 25 08:39:43 2016 +0200
Merge branch 'linus'
So I thought it might be Josh's patch above and reverted it. No joy.
Then I remembered that I enabled CONFIG_RANDOMIZE_MEMORY for the
microcode loader breakage which we've been debugging. Turned that off
and machine resumes fine again.
It looks like
0483e1fa6e09 ("x86/mm: Implement ASLR for kernel memory regions")
broke a bunch of things. Off the top of my head, we probably should make
suspend to disk and CONFIG_RANDOMIZE_MEMORY mutually exclusive, like it
was the case with ASLR previously, AFAIR.
Adding more people to CC and leaving in the rest for reference.
