Has anybody an Idea which could cause this and how to get rid of it?

Is this specific to the kernel or the driver, i.e. does the 418.43 driver work in your setup with a 4.x kernel?

Yeah, it does work with prior kernels. Then only this appeared in journal when shutting down.

Hello,
so, this is all of support I get?
Is the fix for this Bug a Downgrade?

Regards

Most bugs are silently fixed. So you can only sit and wait until the next driver is released, test that and report back. Meanwhile, downgrade the kernel.

Thank you, I will do so.

Regards

Hello,

please take a look at https://bbs.archlinux.org/viewtopic.php?pid=1837028#p1837028, this seems to cause the problem.

Regards
