That one is really very useful. The error handling is leaving some kind of IRQ status no cleared which in turn brings the house down. I think there are two different things in the log here - one is the empty port, the other is some kind of other failure. With a current -mm kernel can you stick ATA_FLAG_DETECT_POLLING on the various .flags = ATA_FLAG_SLAVE_POSS|.... lines for each ata_port_info structure in hpt37x_init_one then see if the identify behaviour is happier. That recipe is probably what we need to do for all the PATA chips that don't have reliable device presence bits.
