This is usually caused by inferior code not setting a fake ptid for the 
UI. This is a very common problem with non-native targets. You can check 
this by inspecting the function gdb_target_has_execution. Check out what 
  the remote target does in extended_remote_create_inferior_1 (it sets 
inferior_ptid to some made up non-NULL entity). The value does not 
matter -- that it is non-NULL is all that is required.

Open a console window and type "list". If gdb does not return something, 
than Insight cannot, either. Insight will disassemble around $PC *if* 
gdb can find a function containing the PC (so that it knows the bounds 
of the function to disassemble). This is a gdb limitation that Insight 
has not worked around yet (and probably never will).
