I'm facing some problem while inserting a new driver module. Getting the following error on module insertion: "Unresolved Symbol Prefetch". The header file "prefetch.h" has been included but still getting the same error. I'm using the kernel version - 2.4.20. Can anyone help me out, pls.

I too have been trying to figure out this unresolved error for prefetch symbols. Your -O2 suggestion worked like a champ. Thanks man!
