Same problem here with Ubuntu 20.04 on a Dell XPS 15 9500, but in my case it was triggered by update from kernel 5.11.0-38-generic to 5.11.0-40-generic.
Apt history shows the update as occurring last Friday morning, and the next time I rebooted (the day after) the WiFi module stopped working, message in dmesg as above. After the error, the WiFi module is not even visible to the BIOS. The only way to get the WiFi module to appear again is to remove the back of the laptop and disconnect the battery, but if I boot Linux it immediately is knocked out again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1950492 Title: wifi stops working on Dell XPS 9310 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1950492/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
