Public bug reported: I am running Ubuntu 20.04.3:
$ lsb_release -rd Description: Ubuntu 20.04.3 LTS Release: 20.04 I am running Ubuntu on a Lenovo ThinkPad P14s with Intel Wi-Fi 6 AX210 Wi-Fi interface. This used to work up to kernel 5.11.0-46 (which loaded iwlwifi "firmware version 59.601f3a66.0 ty-a0-gf-a0-59.ucode op_mode iwlmvm"). Recently, Ubuntu auto-upgraded my kernel to first version 5.13.0-25 and then 5.13.0-27. Both of these kernel versions load iwlwifi "firmware version 63.c04f3485.0 ty-a0-gf-a0-63.ucode op_mode iwlmvm" and then my Wi-Fi interface no longer works. This is the error output from `dmesg` when running kernel 5.13.0-25: [ 68.475159] iwlwifi 0000:09:00.0: enabling device (0000 -> 0002) [ 68.488513] iwlwifi 0000:09:00.0: api flags index 2 larger than supported by driver [ 68.488533] iwlwifi 0000:09:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 0.0.2.25 [ 68.489009] iwlwifi 0000:09:00.0: loaded firmware version 63.c04f3485.0 ty-a0-gf-a0-63.ucode op_mode iwlmvm [ 68.623466] iwlwifi 0000:09:00.0: Detected Intel(R) Wi-Fi 6 AX210 160MHz, REV=0x420 [ 68.803885] iwlwifi 0000:09:00.0: Microcode SW error detected.
