PCIe to PCI-Bridge XIO2001

Hello QNX supporters!
IS there any prblem known about PCIe to PCI-bridges.
In my actual test PC (SIEMENS) there is a PCIe2PCI-Bridge of Texas called "XIO2001".
With this bridge I cannot get the interrupts back from the PCI devices inserted. Therefore no network card or additional
 serial card is worrking properly.
The drivers are running but there is no feedback from the cards, e.g. the "netinfo -L1" tells my that there are packages
 going out but nothing received. If A use sysmon to check received interrupts, I see that no interrupts are routed to 
the QNX4 OS.
With QNX6 ore Debian7 this is working properly.

Re: PCIe to PCI-Bridge XIO2001

Please can you supply the output from ³show_pci -v². When running QNX6,
are you running the apic version or the bios version?

Re: PCIe to PCI-Bridge XIO2001

Hello Hugh, and sorry for the delay. I got no automatic mail and havent checked the forum.

during further tests I found out that Linux will not work if you disable the APIC.
Therefore I got a request to the hrdware vendor SIEMENS. The show_pic I will send as soon as I have access to the 
hardware again.
