My driver module is causing a GPF. The Oops is telling me it occurs in func_a() at offset 0xD5. I've done a # objdump -D -g mymod.o But this only gets me the assembly for that function. My assembly is poor at best. Is there a way to splice in the C code for that function so I can see the offending C code line ? I've read the IBM presentation at http://www-124.ibm.com/linux/presentations/lwce2002sf/debug/Debug_linuxworld 2002.pdf But that doesn't discuss matching the C code to the offset. GDB matches up code to assembly (I think?) so this must be possible...right ? I haven't compiled with optimizations.
