[Fixed] iwlwifi broke with recent upgrade 6.1.43-vendor-rk35xx

[specs]

Current kernel:

Linux rock-5b 6.1.43-vendor-rk35xx #1 SMP Mon Mar 18 05:06:52 UTC 2024 aarch64 GNU/Linux

Symptoms:

$ lspci
..
0002:20:00.0 PCI bridge: Rockchip Electronics Co., Ltd RK3588 (rev 01)
0002:21:00.0 Network controller: Intel Corporation Wi-Fi 6 AX210/AX211/AX411 160MHz (rev 1a)

0004:41:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)

And after a reboot I find with dmesg:

# modprobe iwlwifi

Manually installing the iwlwifi driver yields:

# modprobe iwlwifi
modprobe: ERROR: could not insert 'iwlwifi': Exec format error

 

Perhaps more people ran into the same problem?

 

Of course I ran into this problem while quickly trying to access some server, only finding that the wifi adapter was not working anymore ("it used to work").

The quick & dirty solution was finding a cable bypassing wifi.

Finally found the problem:

Since the kernel was half installed, the kernel and the modules did not match. This means all the modules did not work.

Manually remounting the /boot partition and reinstalling the kernel did the trick.

 

There is still some detail that the "uname -a" and "cat /proc/version" are not updated, although the kernel was replaced.
