Date: Wed, 12 Mar 2008 01:07:27 +0100 From: Holger Macht <hmacht@...e.de> To: linux-acpi@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Kristen Carlson Accardi <kristen.c.accardi@...el.com>, Len Brown <lenb@...nel.org> Subject: [PATCH] ACPI: Set flag DOCK_UNDOCKING when triggered via sysfs begin_undock() is only called when triggered via a acpi notify handler (pressing the undock button on the dock station), but complete_undock() is always called after the eject. So if a undock is triggered through a sysfs write, the flag DOCK_UNDOCKING has to be set for the dock station, too. Otherwise this will freeze the system hard.
