Seems like it's a regression in the firmware.
The issue happens in version 80007E00 but not version 80006E00.
I am not sure how to downgrade it under Linux though.
The firmware changelog [1] is very interesting:
- Improves the performance of the solid-state drive (SSD) by distributing
power into the SSD efficiently according to the power state of the system.
