Best bet would be to use 'git bisect' to locate the exact commit that
caused this, and post the bisection result along with your config.
AFAIK, nobody else is seeing this, is the kernel virgin source?
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.
