Hi 1. I compiled the 8139too.c with the version and include path. But when i tried to insmod it gives unresolved symbol pci_map_single unresolved symbol ioremap unresolved symbol pci_unmap_single when i checked in /proc/ksyms i was able to find the symbol for ioremap but not for the other 2 function calls. can anyone let me know why this is happening ? do i have to recompile the kernel again for the insmod to work with the functions ? I am using RH7.1 kernel 2.4.2 2. can i add my driver as an option to the menuconfig => network drivers if i want to recompile my new driver with the kernel ?
