Ah yes, that was what I was going to try next, if I didn't hear back from anyone :)
I'll let you know if that changes anything. This box has been hanging for a little while now, on an inconsistent basis -- this was just the first time I was able to grab these traces. And by hanging hard, I mean no console, serial or physical, no SysRq, nothing. It's all rather odd.
Will keep you posted.
