AcerLabs/ULi SATA woes

[Bruce M. Simpson]

A workaround for this issue posted here works for me with 6.2-STABLE:

I plan to commit it on HEAD and RELENG_6 as soon as possible, as it 
fixes the regression introduced last year. It seems acceptable that the 
AHCI controller be degraded to legacy mode until such time as AHCI mode 
may be reliably enabled on this hardware. I don't have time to implement 
a better fix.

It seems there has been some Linux activity from the vendor. The 
controller on my system is the one described in the patch set for Linux:
