I did some experiments to get our "good old" Linksys WRT54G
running with recent trunk r43602 / kernel 3.14.26. We are only
using it in adhoc-mode (with olsrd) and it is working OK.
But there is still an issue, but i think it has to do with the
design of the bootup-process:
if wifi is enabled, the box has a lot of (see below [1])
# "irq/4-b43: page allocation failure: order:3, mode:0x204020"
during bootup and is "laggy" / unresponsive.
if wifi is disabled and we do after bootup a
uci set wireless.radio0.disabled=0; wifi
there are no problems and even 4000 kb free ram.
I havent opened a ticket on bugtracker, because it
is no bug 8-)
question: will procd fire init-scripts in parallel?
question: hotplug-events are queued and run one after another, right?
bye, bastian.
