Hi Darren,

I've tried simply hacking the PCI ID into the table in ahci.c with the 
following lack of effect:

[    1.626120] ahci 0000:00:1f.2: version 3.0
[    1.626147] ahci 0000:00:1f.2: PCI INT B -> GSI 19 (level, low) -> 
IRQ 19
[    1.626181] ahci 0000:00:1f.2: PCI INT B disabled
[    1.626194] ahci: probe of 0000:00:1f.2 failed with error -22

It sounds like you got a bit further.  I can't find exactly what patch 
from Matthew you're talking about.  Can you post a pointer?  What does 
it do other than adjust the PCI ID?


Phil.
