• Model: lemp11
• BIOS version: 2022-07-05_62f4da9
• EC version: 2022-07-05_62f4da9
• OS: Pop!_OS 22.04

lemp11 fails to reach S0ix when a SATA drive is unmounted and stopped. On resume, the system is unresponsive.

Steps to reproduce

• Install SATA M.2 drive
• Power on system
• Unmount drive if it is mounted
• Remove AC power
• Wait for kernel to stop SATA drive
• Suspend the system

Expected behavior

• The system enters S0ix (blinking power LED)
• The system resumes to GDM

Actual behavior

• The system does not reach S0ix (solid power LED)
• The system becomes unresponsive with only a blinking cursor

Additional info

You can tell when the drive is powered off when this shows up in dmesg:

sd 1:0:0:0: [sda] Synchronizing SCSI cache
sd 1:0:0:0: [sda] Stopping disk

Also happens on addd02860a1a.

Needs to be retested now that S3 is used.
