Hi all,

I'm not sure why a Kernel 4.12.0-rc2+ is used here, but I do not get any 
problems on the my latest 5.0.0-06622-g1fc1cd8399ab tree and I strongly 
assume this patch showing up in 4.12-rc6

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit?id=74b7b490886852582d986a33443c2ffa50970169

fixes the problem.

Best regards,
Oliver
