I checked with Matthew and found Matthew only applied the first patch [1]; after I applied the second patch [2], I'm no longer seeing any crash or memory corruption issue in Matthew's VM.
BTW, the Windows Server 2019 host running Matthew's VM doesn't work with NIC SR-IOV correctly: when SR-IOV is enabled, the host offers an Intel VF NIC to the VM, then immediately removes/rescinds the VF (this causes hv_pci_probe() to fail and the bug on its error handling path is triggered), and never re-offers the VF, i.e. NIC SR-IOV doesn't work on this host, but that's a host bug and the host team needs to investigate that.
