I've started to observe similar lines in the logs after updating to fresh -CURRENT, upon resume (on a different laptop though, not T410): pcib0: failed to set ACPI power state D2 on \_SB_.PCI0: AE_BAD_PARAMETER acpi0: cleared fixed power button status If these messages are legit, I'm wondering why I didn't see them on 8.4, and if it might affect suspend/resume sequence (broken right now)? Thanks, ./danfe
