--- Comment #21 from Vincenzo Maffione <vmaffione@FreeBSD.org> ---
I'm pretty sure what you see is the effect of a separate bug.

It's a regression introduced by porting netmap to iflib. It shows up with t=
hose
devices that use multiple "free lists" on the receive side. (e.g. isc_nfl >=
 1).
vmx is one of those devices.
I still have to find the time to look into that (e.g., figure out how these
free lists actually work).

Please feel free to open a separate bug, since this one is about the kernel
crash, and it's fixed.
