Egbert should be able to test it.

xc/programs/Xserver/hw/xfree86/os-support/bus/zx1PCI.c: xf86PostScanZX1()
[...]
    /* Add the fake bus' host bridge */
    if (++idx >= MAX_PCI_DEVICES)
        FatalError("HP ZX1:  No room for fake Host-to-PCI bridge\n");

xc/programs/Xserver/hw/xfree86/os-support/bus/Pci.h: 
[...]
#define MAX_PCI_DEVICES 128       /* Max number of devices accomodated */

I remember this value having increased from 64 to 128 in the past.
Comment 5 Stefan Dirsch 2005-11-16 08:11:48 UTC 
Could you figure out, what's the value of idx in your case?
Comment 6 Andreas Schwab 2005-11-21 12:28:43 UTC 
See the log file.

$ grep -c 'PCI.*chip' Xorg.0.log
128

Comment 8 Stefan Dirsch 2005-11-21 13:43:52 UTC 
Thanks. So the PCI devices with BusID > c0 are bogus (duplicates). I thought you had some new crazy hardware with more than 128 devices. I ddn't look closer at the Vendor/Device IDs.
Comment 9 Stefan Dirsch 2005-11-21 15:39:05 UTC 
Egbert will take care of this.
Comment 10 Egbert Eich 2005-11-24 17:34:49 UTC 
Andreas, before I drag this bug bulky thing out from underneath the table and trun it on killing my ears - can't you give me a box where I can log in and test this?
Preferrably with a built tree somewhere?
Comment 11 Andreas Schwab 2005-11-24 17:56:58 UTC 
You should have one yourself.  It happens on the HP zx2000.
Comment 12 Egbert Eich 2005-11-25 07:51:45 UTC 
Andreas, please reread #10 for reason for asking. If you confirm that you have *no* zx2000 available I will try mine. 
Furthermore: currently I have SLES9 installed. If I need 10.1 for testing I may not be able to test this before January.
Comment 13 Andreas Schwab 2005-11-25 15:19:46 UTC 
I'm sorry for wasting your time, but this is actually the effect of the patch from bug 132308.  I'll move this issue to the other bug.
