[SOLVED] PCIe marked as “broken” – retraining fails
Hello everyone,
I was browsing through the journal and I noticed I had some suspicious lines, in particular, I am referring to:
apr 28 18:12:14 archlinux kernel: pci 0000:06:00.0: broken device, retraining non-functional downstream link at 2.5GT/s
apr 28 18:12:14 archlinux kernel: pci 0000:06:00.0: retraining failed

Kernel modules: shpchpI tried different kernels, arch, zen, cachy, they all had the same error, I also reset the bios but nothing changed.
I can't understand if it is a software problem or hardware due to a malfunction.
The only thing I know is that MSI had and maybe still has some throttling problems on the pcie lines, a problem that I have never had.
My devices correctly report:
9070 XT-> LnkSta: Speed 32GT/s, Width x16
980 Pro -> LnkSta: Speed 16GT/s, Width x4
970 Evo -> LnkSta: Speed 8GT/s, Width x4I don't know if something changes under load, I haven't verified this phenomenon and I haven't had any specific problem that would worry me in the sense.
Could some kind soul enlighten me?
Spec:
9800X3D
B850M Mortar
32GB DDR5 6000mt/s
980 Pro
970 Evo Plus
RX 9070 XT

Re: [SOLVED] PCIe marked as “broken” – retraining fails
2.5GT/s is PCIe 1.0, if that failed the chip would not work.
Please post your complete system journal for the boot:
sudo journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'Offline

I think it's relevant, I saw that in the PCI topology tree, the two devices appear not connected to any device.

\-18.7Now, assuming that the two chipset devices aren't actually connected to anything and that they're neither the front nor the rear USB ports. So they could be connected to PCI_E2, M2_3, USBC1, or any other device, my question now is, even if the slots aren't populated—which would partially explain, at least for me, the fact that it's limited to 2.5GT/s (it's PCIe 1.0)—does it still make sense for the kernel to try to train them, or is it the firmware's fault that doesn't disable them?

Apparently this is a known issue on ASMedia and since the port doesn't flicker already addressed - If you're not missing any devices (features like wifi/bt or some usb port being dead) this is probably just an artifact of the hardware (and the firmware to blame)

Everything works fine, so yes, I think it's just an artifact, again thanks so much for the help!
Do you think I need to report somewhere or to someone?
