Problem on unresolved symbol

Dear all,

In my driver, I use the request_8xxirq() to connect my ISR function to IRQ. Building is OK, but, when I use insmod to load this module into kernel, it report " unresolved symbol request_8xxirq ". I found that in fcc_enet.c, it also use request_8xxirq() to do. Why does my action unsuccessed ?

Could you help me?

Thanks in advance!
John
