The firmware provided by Ubuntu 18.04 is too old and causes frequent
system freezes, particularly when using the web browser.
When it freezes, the mouse is the only thing that works, but the GPU gets
completely locked up. Keyboard also gets locked up (even Num Lock doesn't
respond).
There are no crash reports automatically generated. The logs get corrupted so
it's impossible to know what happened.
Updating it to a new firmware version fixes all freezes and system
stability becomes rock solid. I'm not sure which exactly is the relevant
firmware file, but I'm using these:

There's the possibility that I'm wrong and the actually firmware file is
not related to Raven Ridge (I doubt it, my usage when it freezes points
to being a GPU problem)
More specifically I'm using these
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/tag/?h=20190815
I have been working with these new firmware files for months and no
crashes. Yesterday linux-firmware was updated reverting my changes, and
it started locking up again.
