Subject: Suspend-to-ram/resume regression with commit ca37e57bbe0c
Date: Tue, 28 Nov 2017 16:35:26 +0200	[thread overview]
Message-ID: <0fede9f9-88b0-a6e7-1027-dfb2019b8ef2@linux.intel.com> (raw)

Hi

Suspend-to-ram and resume stopped working on v4.15-rc1 and I bisected it 
to commit ca37e57bbe0c ("x86/entry/64: Add missing irqflags tracing to 
native_load_gs_index()").

I noticed it on Intel Kabylake (core) and Apollolake (atom) based 
prototype machines. Symptoms are that machine appears to enter into 
suspend but resumes instantly and hangs. Unfortunately no logs.

If I revert ca37e57bbe0c on v4.15-rc1 it works as expected.
