kern/142728: Panic: Fatal trap 12 in g_io_request

I'm new at trying to find kernel panics. As I said, I cannot seem
to get a dump. From looking at the Instruction pointer, it looks like
the g_io_request function is attempting to work with a g_consumer
that refers to a g_provider that has been freed. The "pp" points off
to a page that is not in its address space (trap 12) or doens't belong
to it (trap 9). The instruction pointer refers to the attempt to retrieve
pp->name as the parameter for the g_trace(G_T_BIO, ... ).
Since the process that is listed as the "current process"
varies a lot, I suspect that the trap is being caused by some event
such as an interrupt.
Could someone please give me some hints on how I might proceed
to 1) get more information or 2) get this problem to a point where
it can be diagnosed and resolved.
