BCM43430: firmware has halted or crashed

[jayofelony]

Hello once more,
uname -a:
Linux jayofelony 6.6.31+rpt-rpi-v6 #1 Raspbian 1:6.6.31-1+rpt1 (2024-05-29) armv6l GNU/Linux

I ran into this issue after which the monitor mode quits, this is a copy/paste from journalctl -xe. Patched using the bcm43430/7_45_41_46 on a RPi 0W running latest Bookworm raspios kernel 6.6.y. No rush or anything, not even sure if this is the info you need. If you need more info let me know.

@DrSchottky, forgive me for tagging you in this. But you also have quite the knowledge in this matter I think. 2 know more than 1.

[DrSchottky]

That's a driver bug (sdio workqueue still processing data after a detach) but it's triggered by a module crash, non included in the log.
Not very useful.

[jayofelony]

Okay, thanks for the clarification so far. I will wait for Matthias to respond if he needs anything else from me.

This is some extra logs from dmesg -w whilst the crash happens. If I know the debug code I can maybe get some more specific data from the driver itself?
