NWAM Debug messages
I don't know if this is suspend/resume related, but it just happened after I
resumed - although I admit the environment would have changed too since I was
trying to use Wireless on resume, when I was using wired before.
Anyway, what's happened is that nwamd seems to be stuck (as in the stacktrace
below) and as such nothing can interact with it, and it's not getting to the
point where it can start any networks.
One major point is that I've most recently started running the nwam-maanger
daemon all the time - to catch issues with it - so it's crashed too...
I'm attaching some logs and a core I grabbed - note this is the non-debug
build, sorry.
ipcs -qa output the following:
