This is probably the same known bug, I think in the kernel, that I encountered with 7.1 running with Xen-4.8. I believe upgrading to 8.x will eliminate it. It can be a bit of a chore to upgrade Xen at the same general time as upgrading the kernel, and as I recall it is not necessary (I think I worked around the bug initially by just using the change I found as a quick patch), but it is probably worthwhile to also upgrade Xen (along with all other packages installed in the dom0). For my story about it see my message <m1ei59B-0036t1C@more.local>, posted on 2018/02/03 with the subject "a story of debugging a NetBSD/Xen server crash and hang". -- Greg A.
