dmesg showing the errors and the lockup. using noaccel=1

So a new thinkpad:

Mobile] (rev a1)

Hangs whenever I try to poke at the card. It starts happily enough with

Although that type mismatch is a bit worrying. And I'm not sure what
prints PM: Image not found.

But after a short while it gets pretty busy:

And then kernel proceeds to throw up errors at random places, e.g.

followed by soft lockups and sometimes hard lockups in places
like attempts to walk skb lists.

Adding runpm=0 does away with this issue.

The specific test was with noaccel=1 - it does not seem to change
things for me.

I poked at the ACPI method NVPO and yes it does actually
seem to execute a while loop waiting for some register
to become 0. Which I guess never happens? Because card
is in a low power state and so reads return ffffffff maybe?


X isn't happy even with runpm=0 but that might be a different
issue - I thought runpm=0 might be an easier place to start debugging
things given there are logs of the failure.

Using kernel 4.20.0-rc3 right now.

Userspace bits are from fedora 29:
xorg-x11-drv-nouveau-1.0.15-6.fc29.x86_64

firmware is pretty recent:
linux-firmware-20181008-88.gitc6b6265d.fc29.noarch
