image of oops
The image says the RIP is at kthread_data + 0xb
That implies something went wrong within the workqueue or kthread systems, I've cc'd linux-kernel, but it's a bit of a vague thing to go on and could conceivably be a hardware issue (or some weird thread interaction in linux-next).
The first question would be "does it happen in vanilla 3.6"?

OK, thanks. I was kinda guessing it was from scsi_setup_fs_cmnd when I choose a component, I don't really know that part of the kernel.

I haven't tried 3.6 yet, but I did just rebuild using gcc 4.6.3 to make sure it wasn't compiler related. After that, I will try 3.6 built with gcc 4.7.1. Also, I got this in -mmotm prior to trying linux-next.

oops of next-20121003 compiled with gcc 4.6.3
So yeah, very similar oops under 4.6.3 (looks like all that changed were addresses & such). I'm running 3.6.0 right now.
uugh, but now that I think about it, I didn't use the same config that I was running earlier since oldconfig was asking me tons of questions that were already answered with a previous config (options removed or moved possibly?). To make this complete, I should use my current 3.6.0 config, rebase to next-20121003 and build that.

config-3.6.0-next-20121003 (second)
OK, so I took my .config from 3.6.0-vanilla, ran oldconfig under 3.6.0-next-20121003 (using all default answers) and I have the same oops.

So just to CC LKML, works in vanilla 3.6.0, happens in both -next & -mm, tried compiling with both gcc 4.6.3 & 4.7.1.
