Hi! Thanks for your report.

Side note: is there any relation to the thread[1] you posted this in?

Sorry, I was just posting to the same email list that I had reported
about a different wifi list earlier. No relation to this, but it's a
new wifi issue.

Doesn't look like it from here.

Side note: discussing multiple unrelated issues in one thread increases
the risk a lot that some or all of them are ignored:

What do you mean by that? From later in the mail it sounds like you mean
latest mainline -- is that correct?

It's from linux git pull. It's 6.5-rc but I didn't write that way
becuase Linus's branch is still 6.4 ... that 6.5-rc0 or rc1 should
have more appropriate.

after June 27 crash my whole linux notebook once
iwlwifi is loaded. Anyone seeing this?

I haven't heard of any such problems, but that doesn't have to mean much.

Bisect? Or there's a patch for this?

# modprobe iwlwifi
... Whole system frozen!


Here's my system before the crash ...

Jeff,

Fow what it is worth, my 6.4-git (6.5-rc0?) commit d528014517f2 (pulled today) is working OK with iwlmvm. Lspci says my device is

I think you do need to do a bisection.
