This commit causes a sata error and thus a boot failure:
ACPI: Invalid Power Resource to register!ata1: lost interrupt (Status 0x50)
ata1.00: exception Emask 0x0 SAct 0x0 SErr 0x40000000 action 0x6 frozen
ata1: SError: { }
ata1.00: failed command: READ DMA
Reverting it as following helped:
$ git revert d872818dbbeed1bccf58c7f8c7db432154c802f9
$ git revert 1ac322d0b169c95ce34d55b3ed6d40ce1a5f3a02
$ git revert 332afa656e76458ee9cf0f0d123016a0658539e4
