I run my workstation under FreeBSD 11.1-STABLE/amd64 r331249 with custom ke= rnel including IPv6 support, options DDB, KDB, INVARIANTS and WITNESS. The following sequence of commands produces a panic reliably, including cold-booted single user mode: ifconfig tap0 create up ifconfig lagg0 create up ifconfig lagg0 laggport tap0 ifconfig em0 up ifconfig vlan61 create vlan 61 vlandev em0 ifconfig vlan61 inet 192.168.0.1/24 ifconfig lagg0 laggport em0 # instant panic Panic messages sometimes printed in bright-white and then system jumps to B= IOS POST within a second or so. Sometimes they are pronted in gray then system = just hangs solid without any reaction on Ctrl-Alt-ESC to enter KDB and no crashd= ump generated. Screenshot is attached. --=20 You are receiving this mail because: You are the assignee for the bug.=
