>Description:
At boot time autoconfigure of an O2 Micro single slot PCI-CardBus bridge
fails. The output from autoconfigure goes as follows...
cbb0: <O2Micro OZ6812/6872 PCI-CardBus Bridge> at device 9.0 on pci0
cardbus0: <CardBus bus> on cbb0
pccard0: <16-bit PCCard bus> on cbb0
pcib0: unable to route slot 9 INTA
cbb: Unable to map IRQ...
device_attach: cbb0 attach returned 12
So, there is something odd about how the IRQs work.
When the system has booted a quick check with pciconf (pciconf -l -v)
reports the card as shown below. This gives me the impression that
the card should be a known one.
cbb0@pci0:9:0: class=0x060700 card=0x00000000 chip=0x68721217 rev=0x05 hdr=0x02
vendor = 'O2 Micro Inc'
device = 'OZ6812 CardBus Controller'
class = bridge
subclass = PCI-CardBus
>How-To-Repeat:
You need only the OZ6812/6872 card and boot.
If there is a need for more debug info, just let me know.
For the moment the system in which I found this problem is
just a testing environment. So, producing more test data
should be relatively quick and easy.
>Fix:
None known yet.
