jbarnes| pitti: just wondering if you can gdb your i915.o and do a "list *intel_update_watermarks+0xcf"

Seems I need to build the module with debugging or so:

(gdb) list *intel_update_watermarks+0xcf
No symbol table is loaded. Use the "file" command.

Sorry, this kernel debugging is all new to me :/

I now built the module with "CONFIG_DEBUG_INFO=1 make -C /usr/src/linux-headers-2.6.31-1-generic/ M=`pwd` modules", so they have debug info now and gdb works. But I guess due to the rebuild the offsets were all scrambled, so I need to get the backtrace again. Stay tuned..
