A few more upstream commits to make sure are present:
drivers/hv/
2d0c3b5a... "hv: utils: Invoke the poll function after handshake" (could be the smoking gun here)
ed9ba608... "hv: vss: run only on support host versions" (I think we got this one in another bug)
3cace4a61... "hv: utils: run polling callback always in interrupt context" (We probably got this one as a prereq)
