panic message

Got this while sitting in the train using my Android phone as AP.

This is probably an important clue: 3735928914 = 0xdeadc052

Reviewing my old tickets.

I have not seen this error since.

The NetBSD patch seems relevant though so why not integrated yet ?

I bought a house, stripped a LOT of paint, got married, had a kid? :-P

I'm open to having that patch applied if someone wants to verify it. I'm still trying to figure out a STA crash here...

Have not happened since, close as OBE.
