kernel log with lockup on resume

This is using 4.20.0-rc1-2.g0587eb8. I believe this is the issue I have had in the past where the system does not resume from suspend, or at least the graphics are locked up when I do.

I am able to fix these resume from suspend gpu lockups by using a script to disable C6 states on the CPU before suspend and then enabling C6 states on resume (this uses zenstates.py to set MSR through a systemd sleep script).

Comment 1 Samantha McVey 2018-11-30 03:22:55 UTC 
This seems to have been fixed with Lenovo A485 BIOS 1.11. I haven't encountered any issues even after disabling my script which disabled C6 states before suspend and enabled them again on resume.

Going to close this now.
