Hi folks, I had built and inserted my kernel module, I wanted to debug and I made some changes. Now after removing the old module I am not able to insert the new module at all. I am inserting the module in the development machine itself so no version mismatches. I tried adding and removing other modules and that works fine. The below seem to be all the symbols I am using in my module. Any hint what I may have accidently removed or deleted or what I am missing would be helpful. krn_mod.o: unresolved symbol pci_write_config_byte krn_mod.o: unresolved symbol __generic_copy_from_user krn_mod.o: unresolved symbol kmalloc krn_mod.o: unresolved symbol unregister_chrdev krn_mod.o: unresolved symbol register_chrdev krn_mod.o: unresolved symbol pci_read_config_byte krn_mod.o: unresolved symbol pcibios_present krn_mod.o: unresolved symbol pci_read_config_dword krn_mod.o: unresolved symbol __ioremap krn_mod.o: unresolved symbol pci_read_config_word krn_mod.o: unresolved symbol kfree krn_mod.o: unresolved symbol pci_write_config_dword krn_mod.o: unresolved symbol pci_find_device krn_mod.o: unresolved symbol pci_write_config_word krn_mod.o: unresolved symbol printk krn_mod.o: unresolved symbol __generic_copy_to_user Thanks, Vishwas ____________________________________________________________ Find what you are looking for with the Lycos Yellow Pages http://r.lycos.com/r/yp_emailfooter/http://yellowpages.lycos.com/default.asp?SRC=lycos10 -- Kernelnewbies: Help each other learn about the Linux kernel.
