Public bug reported: On enabling the wifi interface, the laptop crashes (lockup, without further error messages) soon thereafter (10-20s)
Fix is to replace /lib/firmware/iwlwifi-cc-a0-46.ucode with the corresponding file from https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi # - download archive for AX200: cd /tmp curl -O https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi/iwlwifi-cc-46.3cfab8da.0.tgz # - extract tar xvzf iwlwifi-cc-46.3cfab8da.0.tgz # - copy firmware cp iwlwifi-cc-46.3cfab8da.0/iwlwifi-cc-a0-46.ucode /lib/firmware/ My laptop is as follows: System Information Manufacturer: LENOVO Product Name: 20QVCTO1WW Version: ThinkPad X1 Extreme 2nd SKU Number: LENOVO_MT_20QV_BU_Think_FM_ThinkPad X1 Extreme 2nd ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-firmware 1.187.9 [modified: lib/firmware/iwlwifi-cc-a0-46.ucode] ProcVersionSignature: Ubuntu 5.4.0-65.73-generic 5.4.78 Uname: Linux 5.4.0-65-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu27.16 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: sec 1368 F.... pulseaudio /dev/snd/controlC0: sec 1368 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: XFCE Date: Fri Feb 5 23:25:14 2021 Dependencies: InstallationDate: Installed on 2019-09-23 (500 days ago) InstallationMedia: Xubuntu 19.04 "Disco Dingo" - Release amd64 (20190416) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 06cb:00bd Synaptics, Inc.
