WHEA Count - PCI/PCIe Bus Error

[felipe.s.carvalho_qui@hot]

Hi! I just got a new laptop and the hwinfo is counting a WHEA error, specifically the "PCI/PCIe Bus Error". I read a previous discussion (here https://www.hwinfo.com/forum/threads/whea-count.2245/ ), but I could not identify the origin of this problem in my case. Could someone help me with this?

The specs are:

Laptop Gigabyte G5 KC
CPU: intel core i5 - 10500H
RAM: 16 Gb
GPU: RTX 3060 6Gb

Looking into the Event Viewer I notice two things: there are two folders labeled as "Errors" and "Operational".

In Errors folder all errors are the same: Event ID 20. In Operational folder the errors are Event ID 5 and 42.

The only thing I did was to change the original PCIe SSD from slot 0 to slot 1 (which supports PCIe) and put a new sata SSD one in slot 0 (which supports PCIe/sata). I don't know if this could be the reason, but it seems unlikely to me.

It is attached some screenshots (to show what I described previously) and the hwinfo debug file.

Another thing I observed is that these errors started at 2/9/2021 (although I bought this laptop august 2022). I was looking in the installations on this laptop and noticed that the ControlCenter, Intel Wireless Bluetooth, Realtek Card Reader and Realtek Ethernet Controller Driver were installed 2/9/2022. Since in the post I linked previously the Realtek was the issue, maybe it could be my case...

The detail for Event ID 20 is

This error is reported by the "Comet Lake PCH-H - PCI Express Root Port #15" device.
According to your configuration, under this port are the "RealTek RTS5287 PCI-E Card Reader" and "RTL8168B/8111B PCI-E Gigabit Ethernet Adapter" devices located, so the problem is there.

I just edited the post mentioning the error starting date (2021) and the dates in which those realtek card reader and ethernet controler drive were installed. So this is the issue. Do you know how can I solve this problem? Or at least how to run a test to see which one of these devices are causing the problem.

I checked at Windows Update and there was a pending driver update for RealTek Card Reader. It seemed to have solved the problem, since there is no more counts for WHEA at hwinfo! Thank you very much and I hope this simple solution may help someone else.

The error appeared again, but it seems to have lowered the frequency (at least for now). Is it something I should be concerned?

Well, it should not be happening. You should contact your laptop vendor.
