Comment 85 for bug 1958019

Vanilla 5.4.88 doesn't resolve the issue, at least not for me on Kubuntu
20.10. Earlier 5.4 kernels that I've tested in the past have not fixed
the issue.

I'm not really familiar with Arch... but if I can find the Arch patchset
for 5.4.88, I'll try it out and report back.
