similar to: [Bug 61765] New: Regression: null pointer dereference on reboot after switcheroo use

On x86_64-linux (ubuntu 8.04), we now have 3 test fails. This happened as of revision 61765 (see http://google1.osuosl.org:8011/builders/llvm-x86_64-linux/builds/1316). The failure mode is: Failed with unknown error (or has stderr output) at line 1 /usr/bin/ld: error in /tmp/llvm_wwflUD/false.o(.eh_frame); no .eh_frame_hdr table will be created. Failed with unknown error (or has stderr output)

After switcherooing to integrated and starting X, when X fails to start and causes a console switch, we get hit with a hanger (below). Fix by checking if we're already in D3.

While working on a vga_switcheroo handler for Apple's Macbook Pros I stumbled upon a few bugs regarding the usage of nouveau with other switcheroo handlers and module unloading, here are my fixes for them.

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

After a full device powerdown via the optimus power switch, we seem to lose the HDMI device completely on power on, this keep track of whether we had a hdmi audio sub function device at power on, and pokes a magic register to make it reappear after the optimus power switch is thrown. This at least works on my NVC4 machine, probably needs testing on a few other laptops with other nvidia GPUs.
