Ok, your BIOS assigns conflicting resources to ahci0 and hdac0.  HPS' patch 
means that hdac0 claims register reads of ahci0 which breaks things.  The 
patch I posted should help.

I was able to apply the patch to 9 without any difficulties:

% patch < ~/work/patches/pci_fail_reseve.patch 
Hmm...  Looks like a unified diff to me...

That file hasn't changed since 9.1, so no idea why it doesn't work for you.
