https://bugzilla.kernel.org/show_bug.cgi?id=219346 --- Comment #4 from Todd Brandt (todd.e.brandt@xxxxxxxxx) --- ok I just tested with your patch, it fixed S3, but S2idle and S4 are still broken and still hang the system. The only difference is when S2idle or S4 hang the system will display this on the screen: [ OK ] Started Show Plymouth Boot Screen [ OK ] Started Forward Password R#s to Plymouth Directory Watch.plymouth-start.service [ OK ] Reached target Local Encrypted Volumes. systemd-journal-flush.service [ OK ] Finished Flush Journal to Persistent Storange [ OK ] Created slice Slice /system/systemd-backlight Starting Load/Save Screen #f backlight:intel_backlight... [ OK ] Finished Load/Save Screen # of backlight:intel_backlight. systemd-backlight@backlight:intel_backlight.service And it hangs, doesn't respond to any keypresses, it just sits there. So in short the only two changes are: 1) fixes S3 2) leave S2idle and S4 broken but displays a weird status on the screen on hang So this is clearly affecting more than just S3, that timer has some purpose in Amber Lake that breaks when the timer is shut down. -- You may reply to this email to add a comment.
