MSI initiation results in hang state of Linux on MPC-8641

Question asked by shubhanginisingh on Oct 21, 2013

I am facing an issue regarding msi interrupt on mpc-8641, when i generate an msi from on of the end point devices linux kernel- 3.2.28 on mpc-8641 gets hang.

During the booting of linux as i had enabled freescale msi support, i got some messages as Cannot translate IRQ index=0, similar message is displaying for index 0 to 7.

But the msi data and address registers for end devices are getting programmed properly.

What could be reason for this kind of behaviour???
