:
: Status is 0x30000086
: Status is 0x30000820

:
: cbb0: <ENE CB1410 PCI-CardBus Bridge> at device 7.0 on pci2
: cbb0: Found memory at e0202000
: cbb0: Secondary bus is 2
secondary bus 2 on bus 2 is the problem, I think.
: cardbus0: <CardBus bus> on cbb0
: pccard0: <16-bit PCCard bus> on cbb0

: Any ideas ? What are my possibilities/chances to get it work ?
What kind of computer do you have? I have one that I need to 'hack'
to get working. It is a Toshiba Satellite of recent vintage. Its
pcib2 has pci2 as a child, and my cbb device is on pci2 like yours.
It's subordinate bus numbers are wrong on pcib2:
% pciconf -l | grep pcib2
pcib2@pci0:20:4: class=0x060401 card=0x00000000 chip=0x43421002
rev=0x00 hdr=0x01
% pciconf -r pci0:20:4 0x18
20020200
%
This means that the attempt to kludge around this in the cbb driver
fails:
...
cbb0: Secondary bus is 0
cbb0: Secondary bus set to 3 subbus 4
...
because the config cycles aren't making it through. I hacked my
pci_pci.c code to smack a 0xff into offset 0x1b for unit 2, but that's
evil. It may be necessary for you to do as well until I resolve this
issue.
To see if you need to further update cbb, please send the output of:
% sysctl dev.cbb
to me. On my machine it says:
dev.cbb.0.%desc: TI1410 PCI-CardBus Bridge
dev.cbb.0.%driver: cbb
dev.cbb.0.%location: slot=6 function=0
dev.cbb.0.%pnpinfo: vendor=0x104c device=0xac50 subvendor=0x1179 subdevice=0xff10 class=0x060700
dev.cbb.0.%parent: pci2
dev.cbb.0.pribus: 2
dev.cbb.0.secbus: 3
dev.cbb.0.subbus: 4
