Comment 24 for bug 1426216

I'm on Debian sid with a T470 Thinkpad (Linux t470 5.8.0-1-amd64 #1 SMP Debian 5.8.7-1 (2020-09-05) x86_64 GNU/Linux) and this same bug affects me too. I know, my system is not Ubuntu, but I think it's important to let you know that this might be a problem with the upstream kernel code, as opposed to the Ubuntu or Debian packaged kernel. Maybe it's related to something Lenovo specific.
