It's basically this continuously. I use impala to manage iwd but even
if remove it and use iwctl manally, same thing.

Not sure, I can try later.

It's definitely a kernel issue introduced between 6.16 and 6.17. Still
present on 6.18.

Interestingly enough, If I boot to Windows and then reboot to Linux,
it works. But booting directly to Linux fails. That just tells me
firmware loading is broken in some way. Or something is not being
initialized.
