the ethernet cards irq is coming on the line of the cardbus bridge. this
is because the CB_BRIDGE_INTR bit in the bridge control register
isn't set. but there has been no relevant changes to yenta_socket in
the 2.6.10 -> 2.6.11 timeframe as far as i can see. i think it could be
a recent change to cs.c...i'm gonna read thru the code tomorrow or so..
doesn't sound to hard.
