My kernel is two weeks out of date (r333093), so I need > to check whether the more recent changes affect my system as well. > so i've done a bit more debugging on my end. i've even installed the 11.2-BETA branch last night since 11-STABLE worked without issues about a month or so ago. i've set "debug.acpi.resume_beep=1" and when resuming after entering an S3 sleep state the bell rings and does not stop until i do a hard reset (both with i915kms loaded and unloaded). kinda at a loss as to how this could break both CURRENT and basically 11-STABLE. i'm going to make a ubuntu live image and test that, my laptop is a System76 laptop that shipped with ubuntu originally. if that is broken as well then i guess this could be a hardware issue. the good news is that 11.2-BETA and drm-next works great (aside from suspend/resume) :) -p -- Pete Wright pete@nomadlogic.org @nomadlogicLA
