I don't believe there's anything wrong with one card using the same IRQ for both channels, but there does seem to be something strange going on with the first card. Are there any settings in the 39160 BIOS to control whether IRQs are allocated on a per-card (shared) or per-channel (separate) basis? It looks like the card is allocating an IRQ to each channel, but only reporting the allocation of the first (11) back to the PnP BIOS/OS. This in turn causes the second card to pick up and use 11, resulting in the conflict between the two adapters.
