PC> What is the corresponding source line in the kernel sources?
Well, that's the MD code (sys/arch/amd64/amd64/trap.c) dropping into DDB
after the MI code (sys/uvm/uvm_fault.c) returned an error.
PC> Do you have netbsd.gdb from this kernel?
Yes (or I can build it easily).
The problem is I don't get a backtrace. Neither from DDB nor gdb.
The second problem is I don't know anything about UVM.
