From a report this morning: "So I'm using a MT7610U based adapter and updated to 6.1.1 in Arch Linux and it's a complete lockup a few seconds after connecting as other people have said, I'll use the LTS kernel (5.15) in the meanwhile but this is probably going to get a lot of people that use distros with newer kernels." Background: Problem first discovered with kernel 6.1 rc1. Bug report was seen on linux-wireless around the rc5 timeframe. This is an additional bug report. I don't think additional info is needed as I have tested on several distros with various RC's of 6.1 and the problem is 100% reproducible and unavoidable. This is a show stopper bug and will result in widespread reports as distros upgrade to kernel 6.1. Regards, Nick https://github.com/morrownr/USB-WiFi
