This appears that it could be a result of the recent change r354552 "bhyve:= add support for virtio-net mergeable rx buffers", as it added the line of code referenced in the above error: https://svnweb.freebsd.org/base?view=3Drevision&revision=3D354552 The other thing that could be relevant is that this VM was recently upgrade= d to Windows 10 version 1909. However, given the code that is crashing was only added to head 8 days ago, that is my first guess at where the issue is. --=20 You are receiving this mail because: You are the assignee for the bug.=
