Greg, I am not using remote debugging, that's why I made a call to kldsyms (local system) but it only loaded acpi.ko. May be I should try over a serial console. The system wasn't crashed or in db prompt though. As for the question regarding where I got the addresses from, I typed: asf -k -f -s -x modulepath .asf, this created the ".asf" file and its contain was "add-symbol-file /usr/local/src/nren-6.0current/osr_src/if_osr.ko 0xc24b3184 -s .data 0xc24b6900 -s .bss 0xc24b6cc0" then I copied and past it to the kgdb prompt, all went ok. but when I want to list *0xc24b3184, it complained about "No source code available" or something like that. That's where I am puzzled. I will do what you suggested and over serial console and repost if any problems. Thank you, Jerry
