--- Comment #2 from rob2g2 <spam123@bitbert.com> ---
ran into the same problem on a 12.2-RELEASE-p6 system.

Windows sometimes crashes after a few minutes, and bhyve exiting shows:

rdmsr to register 0x3a on vcpu 0
e82545: TSO hdrlen too small for vlan insertion (0 vs 12) -- dropped
e82545: TSO hdrlen too small for vlan insertion (0 vs 12) -- dropped
Assertion failed: (dtype =3D=3D ntype), function e82545_transmit, file
/usr/src/usr.sbin/bhyve/pci_e82545.c, line 1137.
Abort trap
rdmsr to register 0x3a on vcpu 0
Segmentation fault

--=20
