> Starting with kernel 6.1 rc1, mt7612u and mt7610u are hard locking
> systems when connection is established. 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.
