Sure thing.  Here's a quick summary of the problem that I'm seeing.

  + I've got one of these atheros based A/B/G cards:

    It works great in a co-workers laptop running 6.1

  + Setting up ath0 to config via DHCP results in ath0 never getting an
    IP address.  Furthermore, while scanning, it appears to associate
    for only a brief moment and then moves on to other channels.

  + Manually doing `ifconfig ath0 up` results in it associating just fine.

I've tried booting with ACPI disabled and obtained the same results.

The attached files are the output from dmesg and annotated snippets from the console
logs after turning on wlan debugging with this:  `sysctl net.wlan.0.debug=0x00200000`
I've marked the places in the logs where I typed various commands.

I'd be happy to gather more data if that would help.
