Further research made me stumble into this thread: https://archived.forum.manjaro.org/t/sometimes-the-wifi-fails-to-start-with-message-iwlwifi-probe-failed-with-error-110/151805/3 Proceeded to try most of what user tbg suggested (thanks btw) to no avail. As outlined there by username anandp it seems that Windows sets power saving flags, which in fact does and on my system said flag is called "MIMO Power Save Mode" on device properties. Quick fix is to set said power saving flag to off or in my case "No SMPS".
Hello, I was using my laptop with Fedora 31 until now without any problem. But the wifi module suddenly stopped working. I was using a 5.8.16 kernel. from dmesg log: WARNING: CPU: 4 PID: 843 at drivers/net/wireless/intel/iwlwifi/pcie/drv.c:1130 iwl_pci_probe+0x3d5/0x460 [iwlwifi] ... iwlwifi: probe of 0000:00:14.3 failed with error -22 This means that iwl_trans->cfg->num_rbds is not set but it should be set to 512 (see IWL_DEVICE_9000 define) if (iwl_trans->trans_cfg->mq_rx_supported) { if (WARN_ON(!iwl_trans->cfg->num_rbds)) { <<< line 1130 ret = -EINVAL; goto out_free_trans; I sow several recent issues related to iwlwifi changes but none seems to fix the issues: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95189 https://bugs.archlinux.org/task/68071 https://bbs.archlinux.org/viewtopic.php?id=258720 https://bbs.archlinux.org/viewtopic.php?id=257019 lspci -nn: 00:14.3 Network controller [0280]: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 30) DeviceName: Onboard - Ethernet Subsystem: Intel Corporation Device 0000 Flags: fast devsel, IRQ 16 Memory at a4414000 (64-bit, non-prefetchable) [size=16K] Capabilities: [c8] Power Management version 3 Capabilities: [d0] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [40] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [80] MSI-X: Enable- Count=16 Masked- Capabilities: [100] Null Capabilities: [14c] Latency Tolerance Reporting Capabilities: [164] Vendor Specific Information: ID=0010 Rev=0 Len=014 <?> Kernel modules: iwlwifi, wl $ sudo lshw -C network *-network UNCLAIMED description: Network controller product: Cannon Point-LP CNVi [Wireless-AC] vendor: Intel Corporation physical id: 14.3 bus info: pci@0000:00:14.3 version: 30 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix cap_list configuration: latency=0 resources: memory:a4414000-a4417fff I tried to downgrade the iwlwifi-9000-pu-b0-jf-b0-46.ucode firmware used by this device but no success. I downgraded the kernel to the 5.6.6 version and the error message is different and the module seems do more stuff, so I tried to debug using iwlwifi module debug option: sudo rmmod iwlmvm iwlwifi ; sudo modprobe iwlwifi debug=1 (see log file) iwlwifi 0000:00:14.3: OTP is blank iwlwifi 0000:00:14.3: Can't parse empty family 8000 OTP/NVM sections iwlwifi 0000:00:14.3: Failed to read NVM: -61 I have the feeling that the wifi chip is dead.
