From 7dacd955257774668de0e4416f0a9255a2435daa Mon Sep 17 00:00:00 2001 From: Corentin Chary Date: Wed, 6 Jan 2010 22:07:40 +0100 Subject: eeepc-laptop: add hotplug_disable parameter commit 322a1356be96bcc4b97e8e370f6468c821330077 upstream. Some new models need to disable wireless hotplug. For the moment, we don't know excactly what models need that, except 1005HA. Users will be able to use that param as a workaround.
