request_irq issue

[Laxmikant Rashinkar]

Hi,

I have a MPC8347 based board that runs linux-2.6.15.4 and 2.6.27.1.

With the older Linux, my driver is able to successfully request_irq() interrupts 17, 18, 19, 20, 21, 22, 23 & 48.

But with the newer linux, request_irq() works only for 17, 18 & 19. cat /proc/interrupts shows that none of the interrupts above are in use.
Any pointers on why request_irq() is behaving thus?

thanks for your help
