Change the bus_alloc_resource call in pdq_pci_attach() to memres = bus_alloc_resource(dev, SYS_RES_MEMORY, &rid, 0, ~0, 1, RF_ACTIVE|PCI_RF_DENSE); We should either have pci_alloc_resource default to RF_DENSE or panic if neither PCI_RF_DENSE nor PCI_RF_BWX are specified. The current state of affairs makes no sense.. Drew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
