Hey linux-wireless,

I have experienced an allegedly microcode problem with my iwl 9260 device on
my Thinkpad X395 running latest Gentoo, kernel 6.6.51 and linux-firmware from
20240909.

Shortly after the laptop resumes from sleep and reconnects to my Android
phone, using Androids WiFi hotspot feature, the interface fails to transfer
packets.

Here are snippets from my dmesg when the firmware error occurs:
