I haven't tried this yet, but I started up gitk and realized that the
last good commit was the one previous to the bad commit. They where
made 3 minutes apart in the ath5k dir. So I am assuming that the
"Disable BMISS interrupts was not actually at fault. It just doesn't
seem logical now that i look at it.

So I started another bisect of drivers/net/. Is this the main tree you
where talking about or do you think I need to go further into the main
tree? If so, how far?

I don't think this is the case, Only because I haven't noticed it to
be intermittent. Either wicd works on reboot of a new kernel or it
doesn't. Any attempts to get it working fail until I restart with a
good commit of the kernel.

I tried this and this is where the mystery deepens. With .30.1 it
seems that I can connect to my neighbors network using dhcp but I
still can not hook to my own using a static IP. I have not actually
tried conneting with .30.1/dhcp to my own network, but that is the
next step for me if the bisect on drivers/net fails to provide any
stellar results. Once again, downgrading to kernel .29 fixes
everything without changing any of my other settings. I am still 110%
positive this is a kernel module/driver issue. It does make sense, no?

If you have any other bright ideas keep them coming.
