Hi!
I want to use irda on my notebook! I activated all the stuff in the kernel and when i want to load the module irda, i get this:

juliaroberts:~# modprobe irda
FATAL: Error inserting irda (/lib/modules/2.6.13/kernel/net/irda/irda.ko): Unknown symbol in module, or unknown parameter (see dmesg)

and dmesg gives:
...
irda: Unknown symbol crc_ccitt_table

I googled a lot, but found nothing...

juliaroberts:~# uname -a
Linux juliaroberts 2.6.13 #1 SMP Wed Nov 2 00:22:03 CET 2005 i686 GNU/Linux

Has anybody any idea? Thank you!
