foobar, thank you for reporting this and helping make Ubuntu better. Could you please provide the full computer model as noted on the sticker of the computer itself (not from the Bug Description)?

It may be related to the HDMI audio, which I tried to turn off using radeon.audio=0. Below are the lines from the kernel log having to do with snd_hda_intel (which shouldn't be there when radeon.audio=0). I'm trying to _keep the DIS GPU *turned off* in order to save power & keep this laptop cool_. I can't tell who keeps turning the DIS GPU back on, but I'd love to know how to keep the DIS GPU locked OFF.
