From 97c169d39b6846a564dc8d883832e7fef9bdb77d Mon Sep 17 00:00:00 2001 From: Len Brown Date: Tue, 16 Feb 2010 03:30:06 -0500 Subject: ACPI: remove Asus P2B-DS from acpi=ht blacklist We realized when we broke acpi=ht http://bugzilla.kernel.org/show_bug.cgi?id=14886 that acpi=ht is not needed on this box and folks have been using acpi=force on it anyway.
