Sure there are. For one thing, you want to build your kernel with debugging information. A combination of the following (or all of the following) may be useful for you: makeoptions DEBUG=-g options DDB options INVARIANTS options INVARIANT_SUPPORT options DIAGNOSTIC You also should look at the Handbook and read the `debugging' section. In this particular case, you may want to show us the output of `trace' from within the debugger, and particularily, the disassembled function where the fault occurs with the address of the `Instruction Pointer' (in the above screenshot, you had this information) highlighted. > > I can reliably reproduce this by running dnetc for about 20 minutes, so if > there's something I should do to gather more info it shouldn't be a > problem. > > +--- > | Brook Miles > | A spec of cosmic dust... with attitude. > +-------------------------------------- > -- Bosko Milekic * pages.infinit.net/bmilekic/index.html * www.technokratis.com bmilekic@dsuper.net * bmilekic@technokratis.com * b.milekic@marianopolis.edu "Give a man a fish and he will eat for a day.
