   Sometimes I run into this whilst running "ifconfig wi0 up" w/o if_wi.ko
loaded; that is, the "busy bit won't clear, init failed" happens to my
R40(builtin wi miniPCI) regardless of whether or not the WEP is enabled.

   It looks to me that the firmware doesn't ack. properly at that moment
(unfortunately I have no idea about how to fix this); however, the second
retry("kldunload if_wi" then "ifconfig wi0 up" again) works for me.
