Latest iwlwifi update testing from dmesg -a on firmware load:

Finally back home and I upgraded my laptop to 15/stable.

So far, it looks good. I need to try restarting the interface (netif) a few
times as that periodically triggered the familiar panic. I will beat on it
a bit harder soon.

I did get some messages that may not be normal during hte boot, but they
don't seem to have affected anything.

No other messages logged other than a normal ifconfig.
Keeping my fingers crossed that most/all issues are good so this can be
committed to 14.

I also saw the lock order reversal, but I assume that it is not tied to the
interface:
