The following reply was made to PR kern/10886; it has been noted by GNATS.

I'm pretty sure that the reason the driver worked before is that it was manually determining the I/O address to use by reading the PCI configuration registers on the card itself instead of going through pci_map_ports(). But using pci_map_ports() is the right thing to do and it clearly works for other people (including me, even on FreeBSD/alpha). The patch I sent you under separate cover restores the old behavior which should make it work again, however the problem is either a bug in the PCI support code or some peculiarity about your hardware. The xl driver itself is almost certainly not the real problem. The right thing to do is to add some debug code to pci.c or pci_compat.c and find out why pci_map_ports() _and_ pci_map_mem() both fail. What would also be helpful is if you could show the complete dmesg output from your system, with the -v boot flag if possible. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "Mulder, toads just fell from the sky!"
