3.12 nvidia switcheroo regression
by Daniel J Blueman 01 Dec '13

01 Dec '13

Hi Marcin et al, When booting my Macbook Pro into 3.12 and powering off the Nvidia GPU, we see nouveau try to dequeue an item which isn't present, leading to a page-not-present fault. 3.11 works just nice. It looks like I should add some debug, as there aren't event enqueuing/dequeueing debug flags, or as you suggest? http://quora.org/2013/dmesg.txt http://quora.org/2013/config (same as the Ubuntu mainline config) # echo OFF >/sys/kernel/debug/vgaswitcheroo/switch hda-intel 0000:01:00.1: Disabling via VGA-switcheroo hda-intel 0000:01:00.1: Cannot lock devices!
