I really need to hack the reset path to continue printing everything in the queue, not just the frames that were completed. But the TXQ[1] head pointer is pointing to the wrong descriptor. It's pointing to a descriptor that's finished, whose next descriptor is also finished. That makes no sense. I'll have to add some more debugging to -HEAD so to dump out the full set of TX descriptors in the queue. That hopefully will shed some light here. Adrianhome | help
