Lenovo Yoga Pro 7 14IAH10 - iwlwifi fails to recover from suspend

I have recently bought the computer and have encountered a large problem - After resuming from suspend (I used `systemctl suspend` to check this) iwlwifi just utterly fails.

The laptop cannot access the internet, and the CPU usage and fan speed shoot up. Checking dmesg (posted below) it seems that iwlwifi is entering a failed initialization loop that just hogs all of the resources.
The laptop is new, so this is the first time this happens to me and I cannot provide information about previous kernel versions.

Laptop's specification on Lenovo's website: https://psref.lenovo.com/Product/Yoga/Y … 0?tab=spec

iwlwifi logs before suspend:

In order to reduce spam I have only showed two error loops, but these logs (From 4530.068144 to 4530.068161) just keep on repeating. I have tried to find a way to reload the module (Because it does initialize correctly on boot) but I have not found a way to do so. Running `rmmod -f` fails because iwlwifi (Unsurprisingly) has some resources that aren't freed. Setting the interface to down works, but then I get a timeout when I try to set it to up again.

From the error message I assume the error is firmware related, which my chances of finding a 'proper' fix are quite slim. However, I hope to find a software workaround is possible... Or just gather enough information to submit a proper bug report to the relevant places...

Would be glad to receive help on fix suggestions or next steps to take

Try the solution in https://bbs.archlinux.org/viewtopic.php?id=293404 to see if it helps. Besides, you can report the bug in https://bugzilla.kernel.org.

Re: Lenovo Yoga Pro 7 14IAH10 - iwlwifi fails to recover from suspend

I have the same laptop as yours, and I noticed that the script above didn't fully work.
You need to also add iwlmld since this laptop has wifi 7.

The full script is:

#!/bin/sh

case $1/$2 in
	pre/*)
	modprobe -r iwlmld iwlmvm iwlwifi
	;;
	post/*)
	modprobe iwlmld iwlmvm iwlwifi
	;;
esac
