- Enable the kernel debugger as described above - Build the driver in the /usr/src/sys/modules/bce directory with the command "make". - Run the command "nm if_bce.ko | grep dump_stat" in the same directory with the kernel module just built. In my case I only see a symbol for bce_dump_status_block, but there is a second routine called bce_dump_stats_block. In my working build there are 23 functions that start with "bce_dump" but only 8 are displayed with the command "nm if_bce.ko | grep bce_dump". Of course, I also get the symbol not present error when I try to use any of those missing symbols through a "call" command in the debugger.
