congrats!

There seem to be still some issues reported by Linux before the SATA
error and the Oops afterward.

No idea.

This should have been fixed for the other boards already. Make sure you
have these fixes. Also make sure to set these up as separate commits so
review is easier.

The above might be a problem. As coreboot is responsible for setting PCI
up as far as I know, there might be still a problem.

If I were you, I would try to fix the above errors first. Often solving
these, also fixes errors after it too.

Could you attach a diff of the two `kernel_log.txt` (without the time
stamps) please?

Two more ideas coming to my mind. First try to boot from an USB medium
(from SeaBIOS for example) and look how far that goes and if you can
compare lspci output from there. Maybe a newer Linux kernel also helps
there. Try to play with the Linux kernel pata and ahci/libahi. `libahci`
has an option `skip_host_reset` (`/sbin/modinfo libahci`). No idea if
that helps and if there even is an option to avoid setting up the SATA
controller into AHCI mode.


Thanks,

Paul
