and also something that looked like an assertion failure in skb handling in b44_rx, but couldn't see fully due to having a 80x25 terminal and scrolling not working either...
That and 2.5.75 complains that irq are disabled in local_bh_enable(), looks like the locking in b44_poll will need to be adjusted a bit.
Oh well, we're getting there ;) -- Pekka Pietikainen
