undefined symbols of modules

[Josef Angermeier]

Hello,

when i try to compile my kernel extension as modul, i get some undefined 
references. But a look in System.map shows, that the relevant symbols 
are defined in the main kernel. Why then those undefined references ?

Any hint is appreciated!
bye

Josef
