Freeze with kernel error on iwlwifi

ender

Hi, maybe someone could help with a bug since last week update:
laptop freezes when starting a web browser (immediately with firefox/thunderbird or brave, with a delay with chrome). I can still use the connection as long as I don't start a browser.
Here's the related journal error:

Iwlwifi is a Linux kernel driver that supports various intel wireless LAN adaptors. This seems to be what is failing.
Week 37 saw the current Linux kernel updated to version 6.16.5. This might be the cause of your problem.
Try installing and running the LTS Kernel. Do the following from Terminal to see if it fixes it.
sudo eopkg it linux-lts
Reboot and hold down space-bar immediately when you see the bios splash screen. This will display the systemd-boot menu and pause the timer. Then select the LTS kernel and boot.
If this solves your problem then you might want to switch permanently to LTS or maybe wait until the Kernel is updated as this might also fix it.
I hope this helps.
