Good show. So the problem was with the i915drmkms driver (as you suspected).

From your dmesg output:

```
[     1.000000] WARNING: module error: built-in module sequencer can't find builtin dependency `midi'
[     1.000000] WARNING: module error: built-in module sequencer prerequisite midi failed, error 2
```

Looks like you should disable `pseudo-device  sequencer` also.
And possibly, `hdaudio*`-stuff if you don't intend to use it.

```
[     1.026366] hdaudio0 at pci0 dev 27 function 0: HD Audio Controller
[     1.026366] hdaudio0: interrupting at msi1 vec 0
[     1.026366] hdafg0 at hdaudio0: vendor 10ec product 0892
```

Why not: It's not everyday that one sees examples of troubleshooting-by-
rebooting.
