the required file exist but failed to load

I had been using LAN for a while thus I don't really notice when it failed, sorry.

Re: intel wifi chip doesn't work

Is iwlwifi in the initramfs but not the firmware (because you installed that package later)?

Re: intel wifi chip doesn't work

I don't think so, this is quit old system, the firmware package split and followed few rounds of kernel update all has done.

Re: intel wifi chip doesn't work

Can you either unload the iwlwifi module then reload it or as root scan the initrd for iwlwifi `lsinitcpio /boot/initramfs-linux.img | grep iwlwifi` to ensure iwlwifi is not being loaded in the initrd. Please also post the full output of dmesg to show where in the boot iwlwifi is being loaded.

so yes, it is loaded in initrd, but not the request ucode, as it got error.

rmmod returns failure due to iwlmvm

I think it is due to my setting in /etc/mkinitcpio.conf.d/intel-wifi.conf

MODULES+=(iwlmvm iwldvm)

comment it out, regenerate initramfs, and reboot.

without said two modules, the initial boot still lacks wifi, and dmesg still get the same error lines

but a modprobe -r iwlwifi && modprobe iwlwifi makes it on.

???
Please post your complete system journal for the boot:

sudo journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

Also check the initramfs again for iwlwifi

rmmod returns failure due to iwlmvm

modprope -r iwlwifi

in doubt simply first

modprope -r iwlmvm

Re: intel wifi chip doesn't work

`journalctl -b` has no big difference with `dmesg` shows.

the _said two modules_ aka. the modules in

MODULES+=(iwlmvm iwldvm)

remove them doesn't make a change, these two modules seems to be a hack in older setup of PC.

And, as I said, I've remove that line and regenerate initramfs, and I've checked afterward that these modules aren't loaded at later boot.

And again, as I said at last post,

but modprobe -r iwlwifi && modprobe iwlwifi makes it on.

so yes, iwlwifi works in late modprobe, but not during boot -- that is the main problem.

There is no customize setting to load iwlwifi in initramfs/initrd, but it seems to be pulled in automatically by some hook or module. (check above post showing initcpio output)

Yes it does, fo sure the userspace log and also the main point is that we get to see what's actually going on.

Re: intel wifi chip doesn't work

The journal, not the same grep you applied to dmesg - of course you won't get more information then…
