age0 driver power issues - device_attach error 6

[Da Rock]

I'm getting issues similar to what others have seen in the pre-release
7.1. I'm using the release version because it supposedly has this
driver, but the issue is when I'm on battery it'll work and load the
driver, on ac forget it.

Its on a laptop with an iwn device so I'm in for real hell - but thats
for another post. The long and the short of it is: how do I fix it? What
do I need to look at (source wise) to fix the issue and where can I find
more precise info on it? Would an experienced developer (even the
original who wrote the driver) be willing to guide me so I can fix more
of these little issues with drivers until I can get the know how to
write my own?

Cheers
