This says that the card's RX ring is empty. That could be because the
driver fails to allocate any descriptors, though that's not very likely.
Or it might be a bug...

Does it happen every time you try, or only sometimes?

Unrelated. These messages only tell you that the latency on your PCI bus
is slightly higher than expected, and the driver is compensating for it.

This happened all 3 times I booted into the 2.6 kernel. If there is
something you'd like me to try let me know.
