>Description:
After creating a vlan0 device and hooking it to the physical
device fxp0, assignment of an IP address results into a kernel
panic.
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.
