Heh. Core2 lappy uses mwait_idle_with_hints().. unless you boot processor.max_cstate=1 so it doesn't use piece of shite hpet. Q6600 always has idle woes, seemingly because box doesn't do deep enough cstate to make something (acpi?) happy, despite mwait_idle() having worked fine for years. Seems I need to find the cstate dependency spot, and rap it upside the head if I want my core2 boxen to regain happy campers status. -Mike -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
