I have not seen this on my pi3 b. But you might try this https://patchwork.kernel.org/cover/10741389/

pelwell commented 5 years ago

We can backport when that series (or just that commit) is accepted upstream.

adambarta commented 5 years ago

Yes this is on PI Zero W on PI 3 and PI Zero non W everything works.

JamesH65 commented 5 years ago

It appears that the patches referred to have not yet been accepted upstream, so not sure how we proceed on this.
