Add dmesg to image configuration

Hi gurus,

Silly question: I've build this OpenWRT image and need to use dmesg. I have it included in the image but running it gives me:

dmesg: read kernel buffer failed: Function not implemented

I've tried including options in the image using make menuconfig and make kernel_menuconfig but apparently I am not able to find the missing option.

Any clues?


Dmesg (kernel log) is included by default.
To my knowledge there is no need to select anything additional (assuming that you have not disabled it or other kernel options)
