https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D247647 --- 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. --=20 You are receiving this mail because: You are on the CC list for the bug.=
