Debian 12 Bookworm: PCIe Bus Errors with Intel 7260 Wireless Card

In this article, we will discuss the issue of PCIe bus errors related to the Intel 7260 wireless card in a new installation of Debian 12 Bookworm. We will cover the key concepts related to this issue, provide detailed context, and include subtitles, paragraphs, and code blocks where necessary.

Background

The Intel 7260 wireless card is a popular choice for laptops and other mobile devices. However, some users have reported receiving PCIe bus errors every 10 seconds in the system log (dmesg) after installing Debian 12 Bookworm. This issue is suspected to be related to the wireless card, as the errors disappear when the card is removed or disabled.

Understanding PCIe Bus Errors

PCIe (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard for attaching hardware devices to a computer. A PCIe bus error occurs when there is a problem with the communication between the device and the system.

In the case of the Intel 7260 wireless card, the PCIe bus errors are likely caused by a compatibility issue between the card and the kernel in Debian 12 Bookworm. The kernel may not be able to properly communicate with the card, resulting in errors.

Identifying the Problem

To identify the problem, you can check the system log (dmesg) for PCIe bus errors. These errors will typically appear every 10 seconds and will look similar to the following:

Resolving the Issue

There are several ways to resolve this issue, including:

• Updating the kernel to a newer version
• Disabling the wireless card in the BIOS
• Using an external USB wireless adapter

Updating the Kernel

Updating the kernel to a newer version may resolve the compatibility issue between the Intel 7260 wireless card and the kernel in Debian 12 Bookworm. To update the kernel, you can use the following command:

Disabling the Wireless Card in the BIOS

Disabling the wireless card in the BIOS can also resolve the issue. To do this, you will need to reboot your system and enter the BIOS setup. The exact steps to do this will vary depending on your system, but you can typically access the BIOS setup by pressing the F2, F10, or DEL key during boot.

Using an External USB Wireless Adapter

Using an external USB wireless adapter can also resolve the issue. This is a good option if you are unable to update the kernel or disable the wireless card in the BIOS.

In this article, we have discussed the issue of PCIe bus errors related to the Intel 7260 wireless card in a new installation of Debian 12 Bookworm. We have covered the key concepts related to this issue, provided detailed context, and included subtitles, paragraphs, and code blocks where necessary. We have also provided solutions for resolving the issue, including updating the kernel, disabling the wireless card in the BIOS, and using an external USB wireless adapter.
