This is not a problem for the the module exit function or any other function though. There should be a way to tell the kernel that "Look, I dont care where you put the segments of this module but put them at the same place everytime i re-insert the module again (atleast until the next reboot)". Conceptually, this should not be hard to implement (if its not there already) because it is the same kernel & the same unchanged KO module that i am asking it to insert. > > > 2) Is there any way to overcome this problem so that i can debug the > module > > using vmware even though the module is loaded at different addresses? > > AFAIK, again none that I know. > > -- > regards, > > Mulyadi Santosa > Freelance Linux trainer and consultant > > blog: the-hydra.blogspot.com > training: mulyaditraining.blogspot.com >
