Colin,
I'm afraid this is an ongoing issue. I have faced this in 4.4 and 4.13
kernels:

I could map upstream bugs:
https://github.com/zfsonlinux/zfs/issues/5867
https://github.com/zfsonlinux/zfs/pull/6133
https://github.com/zfsonlinux/zfs/issues/6127
And they all look, somehow, related to the issue according to the stack
trace. Bug 5867, the closest, indicates there are 2 or 3 races that
would have been fixed by some commits already included in the upstream
version I'm testing.
I'll try to get a kdump from latest upstream kernel + latest upstream
zfs/spl modules to check if I can visualize what other task is racing
with "cv_wait_common" in all hung tasks.
With that, I'm re-opening this bug and will try to provide better
feedback soon.
