I think you have omitted the numbers after the functions in the trace. A
sample backtrace should look like:

cpu_Debugger() at netbsd:cpu_Debugger+0x4
wskbd_translate() at netbsd:wskbd_translate+0xc4c
wskbd_input() at netbsd:wskbd_input+0xd0

also, page fault trap should print more debugging information.

Please build a kernel with makeoptions DEBUG="-g" and keep the resulting
netbsd.gdb, so that the debugging output is actually useful.
