Comment 1 Saša Janiška 2017-02-09 14:24:07 UTC 
Forgot to add that NM does not properly populate

/etc/resolv.conf

since there is no longer:

nameserver w.x.y.z 

entry.

Can you test on a rawhide kernel? The maintainers mentioned there was a fix https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=52f5631a4c05 that might cause problems
Comment 3 Saša Janiška 2017-02-10 09:32:59 UTC 
Tried with 4.10.0-0.rc7.git3.1.fc26 kernel and it does work!
Comment 4 Troels Arvin 2017-02-20 08:40:10 UTC 
Confirming Saša's observation: Installing kernel-4.10.0-0.rc8.git2.1.fc26 from https://koji.fedoraproject.org/koji/packageinfo?packageID=8 made the problem go away.
Comment 5 Laura Abbott 2017-02-20 16:20:59 UTC 
This fix is now in stable releases. Thanks for reporting and testing.
