Jeff, thanks for the quick feedback.

On the base point, libata has never enabled SMART on its own. That's always up to the BIOS, etc.

OK, clear.

It's possible that the recent addition of ACPI support will cause disks to be in different modes than previously expected. ACPI supplies ATA taskfiles to be pushed to the disk, and who knows what's in there...

Is there a simple way I can have affected users test this? Is there a kernel boot flag or sysctl setting or something else they can use to disable the ACPI stuff so see if the problem then goes away?

The 'noacpi' module option.
