close it until the problem is fixed in the mainline.

You need to either disable netpoll, or upgrade to the latest 2.6.35 kernel which disables netpoll on bridges.

2.6.36 will have working support for bridge netpoll.

Fixed by 573201f36fd9c7c6d5218cdcd9948cee700b277d ("bridge: Partially disable netpoll support") in 2.6.35-rc6.

I can't close bugs, so someone else will have to do that.
