For me it looks as if the AHCI driver is not working for you. It didn't
work before for you, as I didn't really follow this thread: Do you own
different hardware by now? Did you start the ACPI driver? What kernel
are you using? You can try to set the 'verbose' variable in
'repos/os/src/driver/ahci/include/ahci_driver_base.h' to 'true' and look
for an "Int status: x global: x port: x error: x" message. If you don't
get one, the driver is not working and part_blk will be unable to read
the partition table, and thus not announce its block session. If you
don't see the message above, please do as Josef suggested:

Do you have serial output by now? If not, that should be the first thing
to fix.
