This patch prevents atleast the hang, but still the driver(s) can't locate io mem
or resources (i suspect). The interface will not be enabled.
dc0: <Xircom X3201 10/100BaseTX> port 0x2100-0x217f mem \
0x88000000-0x880007ff,0x88000800-0x88000fff irq 11 \
at device 0.0 on cardbus1
dc0: MII without any PHY!
device_attach: dc0 attach returned 6
sio4: configured irq 11 not in bitmap of probed irqs 0
sio4: port may not be enabled
sio4: configured irq 11 not in bitmap of probed irqs 0
sio4: port may not be enabled
cardbus1: <simple comms, UART> at device 0.1 (no driver attached)
cbb1: CardBus card activation failed
I've tried setting hw.pci.allow_unsupported_io_range="1"
but that does not make any difference.
Any clues to get this adaptor working?
