Subject: [REGRESSION] ACPI / nouveau: replace open-coded _DSM code with helper functions
Date: Mon, 17 Feb 2014 16:42:46 +0100 [thread overview]
Message-ID: <53022DF6.9040709@canonical.com> (raw)
This commit breaks loading nouveau on my optimus laptop. I get the following spam in dmesg:

Reverting b072e53b0a27a makes this problem go away.
