Fatal trap 12: page fault while in kernel mode (did not have the chance to write down the entire crash message) The problem exists within a GENERIC kernel using the if_vlan.ko kernel loadable module and also after compiling in 'device vlan' into into a custom kernel. I tried both 5.3-RELEASE and 5.3-STABLE kernel sources. The Hardware is a IBM ThinkPad R30, fxp0 is the built-in Intel NIC. >How-To-Repeat: ifconfig vlan0 create ifconfig vlan0 vlan 1 vlandev fxp0 ifconfig vlan0 inet 192.168.1.1 netmask 255.255.255.0 I suspect the problem with the fxp driver because someone else using a different driver on 5.3-RELEASE could not reproduce the bug. Maybe it's even ThinkPad-specific. >Fix: Unknown to me. >Release-Note: >Audit-Trail: >Unformatted:
