[linux-dvb] insmod budget-ci.ko fails

[Reinhard Nissl <rnissl@gmx.de>]

Hi,

when I insert the current CVS module, I get the following output:

--------------------------------------------------------------

--------------------------------------------------------------

How can I help solving this issue?

BTW: the last working module can be retrieved from CVS on '2004-05-01 20:00'.

Bye.
