lirc_serial not loading

[Jerry G. <ge...@pa...>]

I am getting the following on 2.6.20.4 kernel

[root@mmamd64dual lirc-0.8.1]# modprobe lirc_serial
WARNING: Error inserting lirc_dev 
(/lib/modules/2.6.20.4/misc/lirc_dev.ko): Unknown symbol in module, or 
unknown parameter (see dmesg)

x86_64 x86_64 x86_64 GNU/Linux
[root@mmamd64dual lirc-0.8.1]#

dmesg gives:
lirc_dev: disagrees about version of symbol wake_up_process
lirc_dev: Unknown symbol wake_up_process
lirc_serial: Unknown symbol lirc_unregister_plugin
lirc_serial: Unknown symbol lirc_register_plugin


What have I not gotten right??
