Comment 26 for bug 1839253

I'm uncertain if this channel is still open, but It seems that the problem
has returned. I'm not quite sure why, I think it might be that I didn't
properly update to boot parameters when I was testing kernel 5.3.0 - 994
but either way, it seems that the new kernel isn't a solution.
