>Description:
additions to GENERIC kernel config:
<snip>
options OFED
options SDP
options IPOIB_CM
device ipoib
device mlx4ib
device mlxen
device mthca
<snip>
Upon boot, when running:
ifconfig {igb0,ix0}.$vlanID create
the system kernel panics and reboots. References to vlan and mlx drivers are
included in the output.
Recompiling without the above options, rebooting, and running an ifconfig vlan
create does NOT crash the kernel.
>How-To-Repeat:
enable OFED drivers, per:
https://wiki.freebsd.org/InfiniBand
reboot
as root, run ifconfig ix0.22 create
<<panic>>
>Fix:
perhaps reference bug kern/181931?
