Bug Description

After waking up from sleep, wifi does not work anymore. It looks like the machine is connected to wifi though. If I disable and re-enable the wifi connection, the driver crashes.

The crash is shown is dmesg. I have attached a file that shows what is going on.

I have installed the latest 6.9.9 mainline and the issue does not happen with it. 6.8.0.35 causes issues for me.
