Comment 18 for bug 1826691

So I have reason to believe this is fixed in kernel 5.2 and later by this commit: https://github.com/torvalds/linux/commit/8ae5b1d78d4acbe9755570f26703962877f9108a

Would someone affected be able to check the with a modern kernel if it can still reproduce? On some Renoir hardware I found that as far back as Ubuntu's 5.8 kernel things are working properly with the test application. I can't go much older than that though because of when Renoir was introduced.
