Interrupt handler not called after boot-up
 

Hello,

I want to enable interrupt for a device that doesn't have any. I have done all things that are necessary for it like getting interrupt no and implementing interrupt handler. Now when i boot up ,this interrupt handler is getting called properly but after boot-up, this handler is not called. Where can be the problem? I have checked with mask registers also but no luck. Can anybody help me?

Does this device have a name?

Hi Dijetlo,

Sorry for such a late rply and thank you for such a quick rply. Actually after registering the interrupt, i am freeing them by using free_irq(). I need to do that in exit function. Now it is working fine.

Thanks
