control is not going to interrupt handler when interrupt comes in serial driver
presently i am writing serial driver in linux 2.6,i have enable interrupts,interrupt identification regester is being updated corructly,but interrupt handler is not being invocked.
First i thought that may be generic serial driver's interrupt handler is being invocked when ever an interrupt comes on
IRQ line 4,so i compiled the kernel and made serial driver as module
and i removed it from kernel. Even after also my serial driver's interrupt handler is not invocked.
Please help me to get rid of this problem,
