Hi again, team! Thanks for your fast reply! I still have some troubles on it... he are the results of my tests on the FAQ 3.9: * nm --extern /lib/modules/2.4.16/misc/m7101.o U __check_region_Rf1d0cdab 00000060 ? __module_author 000000e0 ? __module_description 00000028 ? __module_parm_acpi_io 00000037 ? __module_parm_smb_io 00000410 T cleanup_module 00000240 T init_module U ioport_resource_R865ebccd U kfree_R037a0cba U kmalloc_R93d4cfe6 U pci_enable_device_R944b5e42 U pci_find_device_R8b4d5816 > U pci_insert_device U pci_read_config_byte_R3bd38f74 U pci_read_config_word_R013f4ee4 > U pci_remove_device > U pci_setup_device U pci_write_config_byte_Rc19e8242 U pcibios_present_R520a75b9 U printk_R1b7d4074 * grep SYMBOL /proc/ksyms c01bbec8 pci_setup_device_R__ver_pci_setup_device c01bb524 pci_insert_device_R__ver_pci_insert_device c01bb590 pci_remove_device_R__ver_pci_remove_device There are no version numbers! What does it mean? I've compiled against the kernel I'm running. I'm thinking about moving to another kernel version, maybe a 2.5.x, but I don't know if that would help... Can you help me...again? Regards, dyKa.
