Sorry there is typo mistake in kernel version 3.2.24 instead of 3.2.34
Please find the attached boot log and interrupts(/proc/interuupts) log
Added a debug message in _ipipe_grab_irq function to verify the spurious
interrupt occurrence after IACK read
test code pasted below :
count variable is global variable and initialised to zero
*****************************************************************
count++;
irq = ppc_md.get_irq();
if (unlikely(irq == NO_IRQ)) {
__get_cpu_var(irq_stat).spurious_irqs++;
printk("S. %d",count);
return __ipipe_exit_irq(regs);
}
******************************************************************
Continuous odd numbers is printed for spurious interrupt
S. 1
S. 3
S. 5
