Comment 91 for bug 1872001

To save others time, I tested a bunch of kernels yesterday.

5.3.0-51.44 from here:
https://launchpad.net/ubuntu/+source/linux/
still shows the issue.

dmesg:

The latest mainline kernels 5.6.7, 5.4.35, and drm-tip as of 2020-04-27 from here:
https://kernel.ubuntu.com/~kernel-ppa/mainline/
Also show the issue.

@kleber-souza: if there was a fix committed, can you please point to where? Glad to test it out.
