Yes, it's a kernel.org kernel.
I found some similar reports, though without much more info:
https://github.com/zfsonlinux/zfs/issues/5036 - kernel 4.7.2, initially attributed to ZFS on Linux, but then reproduced without ZFS
https://github.com/systemd/systemd/issues/4069 - kernel 4.7.2
I'll try to bisect.
