How to fix error??? if it's possible ...

[StefanJ]

I am seeing a similar set of errors.

My system has a MSI motherboard (K9VGM-V AM2 VIA K8M890); I'm using an older Radeon RV370 x300 PCIe card.

This is from dmesg:

I actually didn't realize that they were occurring every few minutes until I saw bang!gh's message.

I get satisfactory features out of the basic radeon driver, but the ATI-supplied fglrx set causes X to fail with messages like this in n Xorg log:

(II) Primary Device is: PCI 02:00:0
(--) Assigning device section with no busID to primary device
(WW) RADEON: No matching Device section for instance (BusID PCI:2:0:1) found
(--) Chipset ATI Radeon X300 (RV370) 5B60 (PCIE) found

Further clues in /var/log/dmesg:

AACPI: PCI Interrupt 0000:02:00.0[A] -> GSI 24 (level, low) -> IRQ 24
[drm] Initialized drm 1.1.0 20060810
PCI: Setting latency timer of device 0000:02:00.0 to 64
[drm] Initialized radeon 1.29.0 20080528 on minor 0

I'm guessing that the two are related.

Perhaps the kernel is having trouble with the PCI probe or PCI resource assignment, and a udev rule might be necessary?

Also: The only PCIe setting I see in this MSI motherboard's BIOS menu is a payload size setting.

[StefanJ]

Oh. Well, I think I found why my system is howling. I found this nuggest of wisdom buried in the support area for my motherboard

"• This mainboard doesn't support any ATI X300 series-based graphic card."

Actually, it does support the board, but not in any of its advanced modes.

Crap.

I hope this is the cause of the PCI-Express device error.

I'll buy a cheap nvidia card and retire the radeon.

I get similar message:

on the same motherboard K9VGM-V AM2 VIA K8M890 with Geforce 8500GT video card
but everything works fine

[Vetal]

I was able to get rid of the error by adding pci=nommconf to kernel attributes.

if that doesn't work try a combination of pci=nommconf, pci=nomsi or iommu=calgary

[japega]

I have the same error message on a ASUS P5VD2-X

Erro message on /var/log/messages

May 21 12:26:31 localhost kernel: +------ PCI-Express Device Error ------+
May 21 12:26:31 localhost kernel: Error Severity : Uncorrected (Non-Fatal)

May 21 12:26:31 localhost kernel: VendorID=1106h, DeviceID=a327h, Bus=00h, Device=02h, Function=00h

I found that the error just get in /var/log/messages when I'm in the graphic mode. If I am on a tty terminal, the error message doesn't appear.

Other thing is that I have this error since I had install Fedora 10, when I had Fedora 9 or Fedora 8 it doesn't pressent the problem.

Any help?

Thanks

[japega]

I was on IRC, #fedora-es FreeNode channel, and whit help of fmaq, Lowercases, broli, gin0, Section1 and the people in this forum I can solve the problem, or I hope so.

I put the "pci=nommconf" string at the end of the kernel string in my grub.conf and the message of the PCI-Express Device Error has desapear.

I hope this information helps anyone else.

Thanks to all, folks.

[Vetal]

yeah that's what said just two posts above )))
