I turned full debugging on for a short moment and saw a lot of deadcode flying by on the console.
Just recording it here to be investigated later. Smells like a buffer/dma issue (hopefully just logging at the wrong place..)

Yeah, we should see if that's coming from the firmware, or coming from bad mbuf handling...

Given it is byte-swapped it probably is from the firmware?
I also got pieces with a lot of this and some other stuff in between.
I haven't had time to investigate this closer but will do as I come across it again.
