Calling
pcic_pci_cardbus_init()
from inside
pcic_pci_pd67xx_init()
to push the INTA-D and ISAIRQ's into the PCI state seems to case things to
no longer freeze up, and I am getting at least some traffic through
without timeouts.
Dw
static void
pcic_pci_pd67xx_init(device_t dev)
{
struct pcic_softc *sc = device_get_softc(dev);
if (sc->csc_route == pcic_iw_pci || sc->func_route == pcic_iw_pci)
device_printf(dev, "PD67xx maybe broken for PCI routing.\n");
#ifdef DIRKX_AT_APACHE_ORG_PRIVATE_HACKS
/* XXX DIRKX lets try SOME routing of sorts */
pcic_pci_cardbus_init(dev);
#endif
