@Dave,

I think he was aiming at the fact someone should investigate the
OpenSUSE way of doing it. If they manage to do it without the
workaround with ata_generic somehow, people could be able to port the
change more easily into Ubuntu.
I make take a look at the code tomorrow if I find the time.

Cheers,
K!

> SRU Justification:
>
> Impact: SATA drives on the MBP 7.1 are not usable as the ahci mode is not working correctly.
>
> Fix: Two patches taken from upstream, which have also been marked for stable inclusion will blacklist the MBP from using AHCI and falling back to the ide driver which works. Second half forces DMA on.
>
> Testcase: See report. Disk drive not usable without the patches.
