This bug, caused by the kernel wifi stack mess up, can manifest in different ways depending on your distro. If your distro uses IWD or wpa_supplicant, it may show differently. If your distro is using NetworkManager or something else, you may see different problems. This is a wifi stack problem and it will affect many parts of the wifi system depending on what is used in your system.
I simply cannot chase bugs until this problem is cleaned up. If you need a stable system to get work done, boot into the last stable kernel and worry about this when a new kernel has flowed into your system.

But you know, I'm not a developer,
Sometimes I wonder if I am a developer. I learned programming back in the dark ages with FORTRAN on an IBM Mainframe. I have a couple of C reference books and I just dig in.
I don't have time to look at this today and all indications are that this is going to blow up over the next week as 6.1.66 finds its way into more distros. I am having a senor moment in that I forget the best place to find the backports that went into 6.1.66 so if you could do some research and find what backports went into 6.1.66, that would be a really good start and a big help.

Hi @Jesus-M
I also saw a report from an Ubuntu user this morning and it sounded like this. He was using kernel 6.2.x.
This sounds like a backport that was just applied to kernel 6.1.66 and the Ubuntu kernel 6.2.x is the problem. Now to figure out what backports were applied to kernel 6.1.66 and figure out which one is the problem. Wanna help?

Sure, happy to help.
But you know, I'm not a developer, so I can help if you tell me what to do and what info you need from me.

hi, I am having basically the same issue on an older kernel, is it possible for you to run dmesg on your system after tring to insert the module? Im curious to see if it errors out in the same way

The same problem occurs in Debian 12 (bookworm). A couple days ago they updated the default kernel:
linux-image-6.1.0-13-amd64 (6.1.55-1) -> linux-image-6.1.0-15-amd64 (6.1.66-1)

6.1.66 is a bad kernel. Here is my post about it:

Thanks @morrownr!
Im still trying to figure out if this issue is indeed the same as mine, since the kernel Im using should technically be independant, but Im not sure since im still very very green at kernel dev work. but the behaviour that @Jesus-M described is the same behaviour I am seeing.
