As kernel 4.11 is planned to be released end of April would it be possible to get at least in Fedora testing or via Koji an intermediate built of 4.10 containing the patch described here?

Comment 1 Peter Bieringer 2017-04-21 06:36:22 UTC

just to be informed that a local rebuilded kernel (4.10.8 and 4.10.10) containing the mentioned patch will fix the issue.

Comment 2 Justin M. Forbes 2017-04-21 12:24:46 UTC

That patch is in the 4.10.12 stable update that I will be building today.
