That patch is no= t yet in any git tree which I pull. AFACIT the machines kepe working OK - there's just some nasty dmesg spe= w. If any machines _are_ breaking then this could cause real problems and = I'd prefer that we either go for a whitelist or arrange to detect the condi= tion and fall back to non-acpi ata.
