Deg Error

[Grizzly]

Hi All

Have googled this but most answers are re 3rd party software

I have Zesty installed on a Asus (AR6P) Laptop when I run 

Sudo lshw -c network (or any lshw really) 

I get "Segmentation error (Core Dumped)"

but if I run 

lshw -c network

I get the warning I should run with Sudo, but it works (AFAICT)

If I boot a live 16.04.2 or 16.10.I get the same thing, not tried 14.04.5 yet

all fully updated of cause

Any ideas how to stop this
