[just got back from vacation, or would have sent this earlier]
FWIW, I'm still leaning towards disabling libata ACPI support by default
for 2.6.21.
Upstream has Alan's fix for the worst PATA problems, but for different
reasons, I think PATA ACPI and SATA ACPI support in libata does not feel
quite ready for prime time in 2.6.21.
Scream now, or hold your peace until 2.6.22... :)
