On Dell Latitude ??90, versions 5.15.0-100 and 6.5.0-25 of the kernel hang upon accessing wired Ethernet unless linux-modules-iwlwifi-generic is installed

[Yann Leprince]

The system hangs with Linux 5.15.0-100 and 6.5.0-25 upon accessing this Ethernet controller:

$ lspci -nn
...
00:1f.6 Ethernet controller [0200]: Intel Corporation Ethernet Connection (4) I219-LM [8086:15d7] (rev 21)

Commands that deal with the network hang forever, e.g. "ip link". The machine must be hard-rebooted (magic sysrq) because systemd also hangs during reboot.

Previous versions work perfectly fine (5.15.0-97 and 6.5.0-21). The issue is specific to the integrated network controller, because it goes away when the Ethernet controller is disabled in the BIOS.

Attached is an extract of the kernel logs under the problematic kernel.

[Yann Leprince (ylep)]

The issue is still present on kernels 6.5.0-26 et 5.15.0-101

[Yann Leprince (ylep)]

It seems that the issue is related to the Wi-Fi card and the iwlwifi driver. It can be fixed by installing the linux-modules-iwlwifi-generic / linux-modules-iwlwifi-generic-hwe-22.04 package, respectively.

Also, the issue seems to only pop up on Dell Latitude ??90 laptops (confirmed on Latitude 7490 and 5590).
