Subject: [patch 39/49] ACPI: dock: avoid check _STA method
Date: Tue, 11 Nov 2008 16:24:15 -0800	[thread overview]
Message-ID: <20081112002415.GN10989@kroah.com> (raw)
In-Reply-To: <20081112002215.GA10989@kroah.com>

[-- Attachment #1: acpi-dock-avoid-check-_sta-method.patch --]
[-- Type: text/plain, Size: 1355 bytes --]

2.6.27-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Shaohua Li <shaohua.li@intel.com>

commit 8b59560a3baf2e7c24e0fb92ea5d09eca92805db upstream.

In some BIOSes, every _STA method call will send a notification again,
this cause freeze. And in some BIOSes, it appears _STA should be called
after _DCK. This tries to avoid calls _STA, and still keep the device
present check.
