dmesg.txt post-freeze

Another hang last night. It's not the touchscreen, nor Thunderbolt, since both
were disabled in BIOS.

I was able to SSH into the machine and poke around some. i915 debug files.

Nothing is displayed in dmesg at default log level.

Today:

* updating to 5.3.0-rc7
* booting `drm.debug=0x1e log_buf_len=4M`
* getting ready to also build `drm-tip`
