Thank you, and sorry for being somewhat slow to respond.

I do not have access to the affected hardware myself.

I've asked users who have reported bugs about this to test these setting
and report back in the following bug-reports:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1850439
https://bugzilla.kernel.org/show_bug.cgi?id=206289
https://bugzilla.redhat.com/show_bug.cgi?id=1834751

I will follow-up when I have heard back from the
bug-reporters.

Regards,

Hans
