I have the same problem with a M.2 AX200 card installed in a laptop running Ubuntu 20.04, with kernel 5.11.0-40-generic. I noticed that the WiFi works fine when I force the driver to load the firmware "iwlwifi-cc-a0-48.ucode" by renaming newer versions of this file, and this also worked with previous kernel releases. After every update of linux-firmware, however, the renamed files are replaced and the WiFi starts crash-looping again. Thus, I am confident that the issue is specific to the newer firmware releases for the AX200: - iwlwifi-cc-a0-55.ucode - iwlwifi-cc-a0-59.ucode - iwlwifi-cc-a0-63.ucode Does anyone know what was changed in these firmware revisions?
For reference, here is the error message printed when iwlwifi-cc-a0-55.ucode is loaded. It repeats over and over until I delete the aforementioned firmware file: [ 215.397707] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-cc-a0-59.ucode failed with error -2 [ 215.397747] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-cc-a0-58.ucode failed with error -2 [ 215.397779] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-cc-a0-57.ucode failed with error -2 [ 215.397810] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-cc-a0-56.ucode failed with error -2 [ 215.398396] iwlwifi 0000:03:00.0: api flags index 2 larger than supported by driver [ 215.398423] iwlwifi 0000:03:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 89.3.35.22 [ 215.398430] iwlwifi 0000:03:00.0: Found debug destination: EXTERNAL_DRAM [ 215.398434] iwlwifi 0000:03:00.0: Found debug configuration: 0 [ 215.399009] iwlwifi 0000:03:00.0: loaded firmware version 55.d9698065.0 cc-a0-55.ucode op_mode iwlmvm [ 215.399106] iwlwifi 0000:03:00.0: Detected Intel(R) Wi-Fi 6 AX200 160MHz, REV=0x340 [ 216.087870] iwlwifi 0000:03:00.0: base HW address: b0:7d:64:dc:49:f2 [ 216.101508] thermal thermal_zone2: failed to read out thermal zone (-61) [ 218.817520] iwlwifi 0000:03:00.0: Error sending BT_CONFIG: time out after 2000ms.
