What kernel version is it?
Comment 2 Andy Shevchenko 2022-01-04 11:07:52 UTC 
The bug is against v4.10, now we are almost at v5.16. Please, retest with the latest kernel and fell free to reopen if the bug is still reproducible.

Note v4.10 is LTS, so if the bug is still there in the latest stable version of it, but there is no such bug in the latest vanilla, try to bisect the fix commit and then you may require to backport it.

Oops, v4.9 and v4.14 are, v4.10 is not LTS (v5.10 is), sorry for the wrong message above. It means if you are okay to switch either to vanilla or whatever LTS kernel, which you want to have working it's fine. But in any case you need to retest with latest vanilla first.
