https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227654 Bug ID: 227654 Summary: [panic] repeatable crash with IPv6+lagg+vlan+em Product: Base System Version: 11.1-STABLE Hardware: Any OS: Any Status: New Keywords: crash Severity: Affects Only Me Priority: --- Component: kern Assignee: net@FreeBSD.org Reporter: eugen@freebsd.org CC: stable@FreeBSD.org Created attachment 192681 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D192681&action= =3Dedit panic screenshot Hi! 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 on the CC list for the bug.=
