Untested idea: check the related process' kernel stack....specificly the first stack frame. Then cross check it with information from http://lxr.linux.no/linux+v2.6.37.2/arch/x86/kernel/entry_32.S or your related arch. the upper most comment written there will show the meaning of each values saved in that stack frame. Then what you need to do is just locate where EAX is... I think that's one of the ways....probably there are more.... -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
