The process in question is dumping very low intensity diagnostics to stderr (5 characters every 1.5 seconds). IN this case stderr is not visible, in that it's in a vesa graphics mode. FWIW this process mediates between a high speed modem on sio0 @ 115.2K and a server process talking to it on a pair of unix domain datagram sockets. Ditching the diagnostics seems to have solved the panics for now but it feels like a race condition that I'll eventually lose at some point down the road...
