Has there been any progress on this?

I thought I ran into a similar problem today (wi0_cmd: busy bit won't clear)
using an up-to-date current.

When I booted with the card plugged in, it would attach and ifconfig OK.
Removing the card and reinserting it caused the "wi0_cmd: busy bit won't
clear" when I went to ifconfig it.

The kernel I was booting had 'options BRIDGE' and the bridge sysctls were
configured (from a hostap test I did before upgrading to current). The
presence of the bridge code was enough to get an illegal channel warning
when the card was inserted.

After removing the bridge option, the card attaches, configs and detaches
fine.
