Can we, in the future, always trigger any such performance damaging "fixups" based on DMI white/black lists? As a rule? This is not the first time I see a vendor push broken crap, and everyone else who did it right get the shaft, because people don't like to add quirks to common code. We get performance enhancement features disabled, mdelays added... And for the do-as-windows-does crowd, they do it on vendor?issued device drivers, which obviously don't hork everyone else's devices. Our equivalent solution is to key things to DMI matches. This is worth keeping in mind, because the ACPI subsystem seems to be a common target for such bad behaviour. -- "One disk to rule them all, One disk to find them.
