Dmesg blacklisting snd_hda_intel module only

Just a little more research: blacklisting snd_hda_intel I got this dmesg. A
call trace is called on gpu turn off but I'm able to continue using my laptop
(no lockup). I'll try to make a debug version so that trace is something
useful.

$ uname -r
3.12.6-1-ARCH
