I like the part identifying the driver.
I'm also okay with having fewer messages tagged with ACPI:

Can we delete the '#' from INTA# in this patch?
I don't think that using hardware polarity notation in kernel messages
clarifies anything, particularly since it is hard-coded and thus possibly
conflicting with the subsequent '(level, low)'...
