Dmesg and GPU hangs

The first kernel that has this problem is 4.18-rc1. The last kernel with this
problem is drm-tip (4.19-rc3, 75bb460b367a614d10b0fba220143bee42657d7e).

Dmesg from 4.18-rc1 is corrupted, but there are parts still readable.

I set netconsole and, as I expected, there was no output. One thing I noticed
is that I connected an optical USB mouse and, after 10 minutes, its LED still
did not turn on.

Last good kernel: 4.17.19
First bad kernel: 4.18-rc1
Latest bad kernel: drm-tip (4.19-rc3,
75bb460b367a614d10b0fba220143bee42657d7e).
