Device: Intel Corporation Wi-Fi 6 AX 200 (rev 1a)
Firmware: 20191022 (2b016af)
On boot the device is detected (shows up in lspci) but the initialization from iwlwifi fails with the following log in dmesg:
$ dmesg |grep iwlwifi
[ 4.983570] iwlwifi 0000:04:00.0: enabling device (0000 -> 0002)
[ 4.983762] iwlwifi 0000:04:00.0: U _iwl_disable_interrupts Disabled interrupts

[ 5.080453] iwlwifi: probe of 0000:04:00.0 failed with error -110
The device does *not* appear as a network interface.
For testing I increased the initialization timeout in iwl_finish_nic_init() from 25000 to 225000 microseconds, which did not help.
The device worked before but stopped at some point (if there is interest, I can try to bisect).
The device works under windows.
After rebooting once into windows it now also works on Linux, even after further reboots.
But the issue definitively happened before. I reproduced it in over 30 consecutive boots. (Even with windows boots in between).
I have encountered this same issue when using Proxmox VE and alternating boots of Windows with Linux.
If the Wi-Fi adapter is passed through to windows, and I shutdown in regular fashion, this error appears both on the host machine or a Linux VM. However, if I disable the WiFi adapter in Windows before shutting down, the adapter is available both in the host, or the Linux VM, if I pass it through.
All of this leads me to think that this is an issue with how Windows interacts with the WiFi adapter, possibly setting some sort of 'claim' flag on the adapter.
Hi - my scenario is as follows. Ubuntu 20.04 (184.108.40.206-generic) on AMD Ryzen platform with backported Intel drivers following the instructions. When I cold boot into Ubuntu, the wireless driver never works. When I boot into Windows and then warm boot into Ubuntu, the wireless driver works. Something seems to be wrong with the Linux drivers?? Replication of scenario is 100%...

I encountered the same issue with Intel 9260 on a dual-boot Ubuntu 18.04 and Windows 10. Disabling fast-boot in Windows solved the issue for me:
Disabling fast-boot in Windows also solved the issue for me. Windows 10, kernel 5.7.0 rc3 and Intel AX200 Wi-Fi adapter.
