Wake from suspend takes 20+ seconds. I believe this ACPI error is the cause, but I'm not sure:
Okt 03 12:53:29 ... PM: suspend entry (deep)
Okt 03 12:55:26 ... ata1.00: Entering standby power mode
Okt 03 12:55:26 ... ACPI Error: Aborting method _SB.PCI0.XHC1._PS0 due to previous error (AE_AML_LOOP_TIMEOUT)

Okt 03 12:55:26 ... ACPI: PM: Preparing to enter system sleep state S3
Okt 03 12:55:26 ... ACPI: PM: Low-level resume complete

Okt 03 12:55:26 ... Restarting tasks ... done.
Okt 03 12:55:26 ... PM: suspend exit
It also seems to happen more often when leave the system suspended for a long time.
Tried, no effect:
- Disabling XHC1 wakeup via
/proc/acpi/wakeup
Has anyone with this model or anyone with a MacBook slow wake issue run into this?
