Bogus PCI vendor ID

Bogus PCI vendor ID

[Kai Ruhnau]

Hi,

I have a problem with two of my PCI devices showing the wrong PCI vendor
ID (0001) in vanilla kernels.

My system currently runs a 32 bit x86 kernel built from ubuntu sources
2.6.20.3-ubuntu1. This is the only kernel I have found so far that shows
the correct PCI IDs:

~ # lspci -n
00:00.0 0600: 1002:7930
00:02.0 0604: 1002:7933
00:06.0 0604: 1002:7936
00:12.0 0106: 1002:4380
00:13.0 0c03: 1002:4387
00:13.1 0c03: 1002:4388
00:13.2 0c03: 1002:4389
00:13.3 0c03: 1002:438a
00:13.4 0c03: 1002:438b
00:13.5 0c03: 1002:4386
00:14.0 0c05: 1002:4385 (rev 13)
00:14.1 0101: 1002:438c
00:14.2 0403: 1002:4383
00:14.3 0601: 1002:438d
00:14.4 0604: 1002:4384
01:00.0 0300: 10de:0193 (rev a2)
02:00.0 0200: 11ab:4364 (rev 12)
03:02.0 0c00: 104c:8024

I tested several vanilla kernels: 2.6.23.1, 2.6.23, 2.6.22, 2.6.21 and
somewhere between 2.6.20 and 2.6.21 via bisect. There, the output of
lspci is as follows:

~ # lspci -n
00:00.0 0600: 1002:7930
00:02.0 0604: 1002:7933
00:06.0 0604: 1002:7936
00:12.0 0106: 1002:4380
00:13.0 0c03: 1002:4387
00:13.1 0c03: 1002:4388
00:13.2 0c03: 1002:4389
00:13.3 0c03: 1002:438a
00:13.4 0c03: 1002:438b
00:13.5 0c03: 1002:4386
00:14.0 0c05: 1002:4385 (rev 13)
00:14.1 0101: 1002:438c
00:14.2 0403: 1002:4383
00:14.3 0601: 1002:438d
00:14.4 0604: 1002:4384
01:00.0 0300: 0001:0193 (rev a2)
02:00.0 0200: 0001:4364 (rev 12)
03:02.0 0c00: 104c:8024

Note the two vendor IDs 0001 for 01:00.0 and 02:00.0.

Since these two devices are my graphics card (PCI express) and network
card (builtin) respectively I have quite some trouble running my system
without the right vendor IDs ;-)
Can this be fixed?

Regards
Kai

No idea but it seems to be plaguing us:

- r8169 + Abit fatal1ty motherboard

(so far nobody reported a 8169 on a fatal1ty motherboard with a
sensible vendor id)

Have you tried doing a cold boot at every test? I've had bogus PCI IDs
appear before where it was the device's fault, and the ID would change
after the first boot.

With LAN devices you may even need to pull the plug because WOL will
keep the device in a warmstart state.

Please try CONFIG_PCI_MMCONFIG=n

If this is the same like the kernel option 'pci=conf1', that fixes the
vendor IDs.

Same effect. Ubuntu and many other distros are shipping kernels with
MMCONFIG off by default for reasons like this. Check to see if you have
an updated BIOS from your motherboard manufacturer?

No, nothing available there. (OEM board, running fine under Vista, I
don't expect to get support there...)

Ah, that's interesting, as Vista is supposed to require working MMCONFIG
support to be certified.
