problem with permanent modification on Sculpt

[Norman Feske]

Hello,

from looking at the log, one can see that the AHCI driver is not even
started, which makes sense when comparing the reported PCI class IDs
against the code of the driver manager that selects the driver [1].

It may be worth checking the BIOS settings for SATA-related options. I
can vaguely remember having seen BIOS options for selecting legacy
support versus AHCI.

Cheers
Norman
