[BUG] iwlwifi failed to load on boot, various kernels

[Davor Saric]

Hello,

I am on Arch linux with Kernel 5.4.85-1-lts. I have also tried recent
kernels and behaviour is the same. I have the issue that after boot
there is no wifi card initialized.
I have error in dmesg: iwlwifi: probe of 0000:06:00.0 failed with error -110

I have to reset it with following:

modprobe -r iwlwifi
echo 1 > /sys/bus/pci/devices/0000\:06\:00.0/reset
modprobe iwlwifi

I see that you mention that disabling Fast boot in windows 10 fixes the
problem. I did that but I do not have problem when doing a reboot from
windows 10 to arch linux. I have problem that when I turn of the PC
while I am in Arch linux and then turning it on tomorrow again and boot
to Arch Linux, my wifi card doesn't initialize.

On 44.415273 I have reset the wifi with above script:

dmesg|grep iwlwifi
  iwlwifi 0000:06:00.0: enabling device (0000 -> 0002)
  iwlwifi: probe of 0000:06:00.0 failed with error -110
reseted -> iwlwifi 0000:06:00.0: loaded firmware version
36.ad812ee0.0 op_mode iwlmvm
iwlwifi 0000:06:00.0: Detected Intel(R) Dual Band
Wireless AC 8265, REV=0x230
iwlwifi 0000:06:00.0: base HW address: f8:34:41:00:77:15
iwlwifi 0000:06:00.0 wlp6s0: renamed from wlan0

Do you have any idea what is the cause of it?
