You could add a print including the backtrace : and see if that function gets called when it freezes.
Ummm. No. Adding a traceback print to a function that's called 60 times a second in steady state doesn't seem like a viable option. : Else I would try to compile a fresh kernel from USB P4.

Is your printout lowercase "wdrain" ? Yes.
