| |
I am having problems with some PCI devices being configured incorrectly. The PCI bus layout is as follows:
# lspci -t -[00]-+-00.0 +-01.0-[01]----00.0 +-07.0 +-07.1 +-07.2 +-07.3 +-08.0 +-09.0-[02]--+-06.0 | +-07.0 | \-09.0 \-0a.0-[03]--+-06.0 +-06.1 \-07.0
All devices except the bridge 00:0a.0 and/or the 03:07.0 device gets configured correctly.
The 03:07.0 device has I/O ports at de00 but the 00:0a.0 bridge is configured to have I/O behind bridge: 0000e000-0000efff. Since de00 is not in this range access to device 03:07.0 is impossible.
If I understand correctly an error like this is caused by a BIOS error. Has anyone else seen problems like this and what is the suggested fix ?
I'm running a 2.2.19 kernel and have tried the bios, nobios and nopeer options to the kernel with the same results.
Thanks in advance,
