The problem is that the given package is not even a WHD event.
So trying to read the EventHeader fails...
Seems like WHD events in reality are Broadcom brcmf events.
#3 should fix this issue.

The issue appears to be related to EventHeader deserializing improperly such that evt_data.datalen is far larger than the real data buffer. I've not identified what the proper offset is for this header. Documentation on what BcdHeader can contain and where EventHeader's format is defined would be appreciated.

Something is up with the deserialization of the EventHeader, none of these values look correct. Note, this trace! was added after evt.byteswap(), but putting it before yields similar, definitely wrong, results.

It makes it further from your fork, but I still get some sort of failure (though it's cryptic and possibly related to my probe)

@chiefnoah, is it still panicing in the event handling?
If you provide the output I can try to understand what the problem is.

No, it gets further. There's a bunch of IOCTL Response messages, but it ultimately fails with some sort of probe error that I've never seen before:

Could it be a power issue?

"Error communicating with probe" is an error from probe-rs , not a panic from the firmware. I'm going to close this (also due to inactivity). If you see a panic please feel free to open a new issue with the stack trace.
