Thanks for your trouble of cleaning up.


I tried the patches you sent just now. Since Socket/DIMM type
configuration was changed in rev 5800, I tested these against rev 5799.

Patching and building is ok. Booting looks fine, Grub2 comes up and
loads Linux. However, Linux cannot find SATA controller, and because of
that, the booting fails. (Although Grub just loaded the kernel and
initrd from SATA.)

Linux gives the following complaints that I have not seen before:

It seems that also the USB controller initialization fails, although I did not test if it worked.

Aside from the AHCI/OHCI/EHCI -drivers failing, the boot logs seem to be the same as before.

I tried to look at the patch code, but could not figure out why this is happening.
