That's a more factual note than your previous. The HP machines tend to have very complicated AML with heavy SMI and EC dependencies. Another vendor which leans this way sometimes is Sony. Some machines do have AML bugs, and the Microsoft/Intel ACPI code bases certainly have workarounds for those problems. Some machines simply use corner areas of ACPI that we handle incorrectly. It takes a lot of effort to find these corner cases and handle them correctly.
