Hi, I'm having an issue with an Intel AX210 wireless module connected to a Raspberry Pi Compute Module 4 using PCI Express. Kernel version is: 6.12.0-1.g52785e2-default (using OpenSUSE microOS 20241114) After boot there is no WIFI interface present. dmesg shows the following error: [ 10.459327] [ T712] iwlwifi 0000:01:00.0: Timeout waiting for PNVM load! [ 10.467497] [ T712] iwlwifi 0000:01:00.0: Failed to start RT ucode: -110 The same error occurs with kernel 6.11.7. However when I flash the CM4 with Ubuntu Server 24.04.1 LTS (using kernel 6.8.0-1010-raspi and firmware ty-a0-gf-a0-86.ucode) then there are no issues and the WIFI interface is present. Full dmesg output for iwlwifi (kernel 6.12.0): [ 9.338062] [ T651] iwlwifi 0000:01:00.0: enabling device (0000 -> 0002) [ 9.350164] [ T651] iwlwifi 0000:01:00.0: Detected crf-id 0x400410, cnv-id 0x400410 wfpm id 0x80000000 [ 9.350186] [ T651] iwlwifi 0000:01:00.0: PCI dev 2725/0024, rev=0x420, rfid=0x10d000 [ 9.350197] [ T651] iwlwifi 0000:01:00.0: Detected Intel(R) Wi-Fi 6 AX210 160MHz [ 9.526723] [ T62] iwlwifi 0000:01:00.0: TLV_FW_FSEQ_VERSION: FSEQ Version: 0.0.2.42 [ 9.528898] [ T62] iwlwifi 0000:01:00.0: loaded firmware version 89.6b44fa0b.0 ty-a0-gf-a0-89.ucode op_mode iwlmvm [ 10.186016] [ T712] iwlwifi 0000:01:00.0: WFPM_UMAC_PD_NOTIFICATION: 0x20 [ 10.186041] [ T712] iwlwifi 0000:01:00.0: WFPM_LMAC2_PD_NOTIFICATION: 0x1f [ 10.186055] [ T712] iwlwifi 0000:01:00.0: WFPM_AUTH_KEY_0: 0x90 [ 10.186068] [ T712] iwlwifi 0000:01:00.0: CNVI_SCU_SEQ_DATA_DW9: 0x0 [ 10.193797] [ T712] iwlwifi 0000:01:00.0: loaded PNVM version 16611aa6 [ 10.459327] [ T712] iwlwifi 0000:01:00.0: Timeout waiting for PNVM load!
