Description Nicolas Mailhot 2005-11-02 05:03:20 UTC

Most recent kernel where this bug did not occur: New system, so no history
Distribution: Fedora Core Devel
Hardware Environment: CK804 based mobo (GA-K8N Ultra 9)
http://www.giga-byte.com.tw/MotherBoard/Products/Products_GA-K8N%20Ultra-9.htm
Software Environment: N/A
Problem Description:

I've just booted on the last Fedora Devel kernel (2.6.14-1.1635_FC5,
based on 2.6.14-git2) and my dmesg is now filled with:

pcie_portdrv_probe->Dev has invalid IRQ. Check vendor BIOS messages.

Should I worry ? Report it somewhere ? Attaching what info ?

A google search shows other motherboards are affected, I don't know if the bug
is in the Linux CK804 code or in the reference bios for the CK804



Steps to reproduce:
Boot, read dmesg

Still there with new F7 bios and 2.6.14-git6

Comment 4 Nicolas Mailhot 2005-11-05 04:54:30 UTC

Also on this CK804 board I get

PCI-DMA: Disabling IOMMU.
pnp: 00:00: ioport range 0x1000-0x107f could not be reserved

Comment 5 Len Brown 2005-11-10 19:23:27 UTC

The PCIE devices that are complaining are PCIE bridges:

00:0b.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3)...
00:0c.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3)...
00:0d.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3)...
00:0e.0 PCI bridge: nVidia Corporation CK804 PCIE Bridge (rev a3)...

Unclear if they're supposed to have IRQs.
Not sure if it is related, but they also advertise MSI capability.

Unclear that this issue is related to ACPI -- maybe a stray
printk from the PCI express code?  booting this bug to PCI category.

Comment 6 Nicolas Mailhot 2005-11-11 03:25:59 UTC

I only put in acpi because the error message mumbled about BIOS. Don't really
know where it belongs

Comment 7 Rajesh Shah 2005-11-14 14:35:27 UTC

The error message indicates that the PCI Express bridges in the system don't 
have any interrupts assigned to them. This is not a problem since the pcie 
bridges in this sysem didn't report any capability that requires an interrupt 
anyway (i.e. they don't support pcie hotplug or advanced error reporting). The 
pcie code is printing a bogus warning that can be ignored in this case.

Comment 8 Greg Kroah-Hartman 2005-11-14 15:16:26 UTC

Ok, we can clean up those error messages, and will in a bit (Rajesh is working
on this area for other cleanups too.)

Am closing as this really isn't a bug.

Thanks for the analysis
