Hi there,

I saw Rafael made this recent commit:
http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=8ad928d52e63a9b7d69f0873d7318c4561e2f8cd

That may not be the culprit at all, sorry. I noticed that if I'm using, say,
the latest drm-intel-next kernel or nouveau kernel ACPI reports nouveau's
status properly, e.g. nouveau: power state changed by ACPI to D3cold, however
in next I no longer get these messages, although the device seems to be in
D3cold (?). At least temperatures are much lower, especially when building
software.

[23301.994315] ACPI Warning: \_SB_.PCI0.P0P2.PEGP._DSM: Argument #4 type
mismatch - Found [Buffer], ACPI requires [Package] (20130725/nsarguments-95)
(That's the only indicator of power transitions now - a warning that might go
away in the future - p.s., do I need to do some DSDT hacking for that or is it
on the Linux-side?)

Invoking lm_sensors' sensors command shows N/A for the nouveau device on
Optimus laptops, as expected if the device is in D3cold.
