Upgrade to linux-firmware-20250613: Intel Wifi not brought up

Hello,

I ran `pacman -Syu` and hit the "linux-firmware" upgrade.
I already performed the `pacman -Rdd linux-firmware` mentionned in the Archlinux.org home page.

It installed the following pckages:

The problem is my Intel Wifi is brought up anymore.

Note that `linux-firmware-intel-20250613.12fe085f-6-any` has been installed.

This is my Wifi device:

08:00.0 Network controller: Intel Corporation Wi-Fi 6 AX200 (rev 1a)
	Subsystem: Intel Corporation Wi-Fi 6 AX200NGW
	Flags: bus master, fast devsel, latency 0, IRQ 17
	Memory at d4400000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [c8] Power Management version 3
	Capabilities: [d0] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [40] Express Endpoint, IntMsgNum 0
	Capabilities: [80] MSI-X: Enable+ Count=16 Masked-
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [14c] Latency Tolerance Reporting
	Capabilities: [154] L1 PM Substates
	Kernel driver in use: iwlwifi
	Kernel modules: iwlwifi

This is what I see in the logs

$ sudo dmesg | grep wifi
[    6.352077] iwlwifi 0000:08:00.0: Detected crf-id 0x3617, cnv-id 0x100530 wfpm id 0x80000000

[    6.352093] iwlwifi 0000:08:00.0: Detected Intel(R) Wi-Fi 6 AX200 160MHz
[    6.352330] iwlwifi 0000:08:00.0: Direct firmware load for iwlwifi-cc-a0-77.ucode failed with error -2
[    6.352333] iwlwifi 0000:08:00.0: no suitable firmware found!
[    6.352334] iwlwifi 0000:08:00.0: iwlwifi-cc-a0-77 is required
[    6.352335] iwlwifi 0000:08:00.0: check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

In order to recover the usage of my Wifi device, I had to:

sudo pacman -U \
    /var/cache/pacman/pkg/linux-firmware-20250508.788aadc8-2-any.pkg.tar.zst \
    /var/cache/pacman/pkg/linux-firmware-whence-20250508.788aadc8-2-any.pkg.tar.zst

What are your advices to use the latest linux-firmware package with my Wifi device?

Re: Upgrade to linux-firmware-20250613: Intel Wifi not brought up

Some reports on interwebs suggest this could be caused by having incorrect files in /usr/lib/firmware .

Try removing linux-firmware again and check what's left in /usr/lib/firmware .
(I expect there is a way to check non-pacman owned files in a folder without removing packages , but I don't know it).

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

usr/lib/firmware/iwlwifi-cc-a0-77.ucode.zst is in linux-firmware-intel, the ENOENT heavly suggests that package wasn't installed at the time?
Might be an issue w/ the initramfs being generated w/o that package and installing it didn't update the initrams?

@seth , I reinstalled  linux-firmware latest package and made sure wlwifi-cc-a0-77.ucode.zst is present.
dmesg showed wlwifi-cc-a0-77 was loaded and used.
but the wireless interface was not up.
I had to get back to downgraded linux-firmware
