Newbie: Unresolved symbol

["vishwas manral" <vishwas.manral@xxxxxxxxx>]

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
