Michael,
When I try the -mb tree on my old i386 notebook, I get an "irq 11: nobody cared"
message and interrupts for the bcm43xx-mac80211 device are not initialized. The
code in Linville's tree works. The only difference that seems to be important
is the code returned when a shared interrupt not intended for us is received.
By making the changes shown below, both trees now work.
I recall you having a discussion with someone over some aspect of shared IRQ's,
but I don't remember the details and I'm too busy (lazy) to go back and look.
Thanks,
Larry
