Can you give any hints as to how we can classify this misconfiguration? Barry's system has a level triggered IRQ assigned to sky2, and that IRQ is not shared: http://bugs.gentoo.org/show_bug.cgi?id=132056#c3 I'm just looking for something I can take to the ACPI developers, other than "its broken because Stephen said so" ;) Thanks.
