Kernel panic log.

I usually get kernel panics on my Alienware M14X R2.

Using Archlinux up to date.
Linux alienarch 3.11.6-1-ARCH #1 SMP PREEMPT Fri Oct 18 23:22:36 CEST 2013

Nouveau is at 9.2.2

Kernel panic log attached.

What else can I do in order to help?

Thanks.

From the code in the trace, looks like node->mem is somehow null. Can you
supply a full dmesg?

Full log

Now having a look to the full log I can see a lot of other things that should
be taken into account. Sorry for cutting the information.

--- Comment #4 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
This can't be good. Happens after switcheroo turns the card off and it goes to
D3cold. I suspect the crash is related to this.

Then, when turning the card back on,

nouveau E[      VM][0000:01:00.0] vm timeout 1: 0xbadf1200 1

Which probably leaves the vm uninitialized (?), and the BUG which happens due
to node->mem being NULL:

Can you check whether this still happens with recent kernels? With 3.13.x the
card should automatically power on/off as needed.
