Am working on a problem where the system hanging after some unequal intervals, with the below o/p printing on the console, Though this might be mostly tighten to the click router module am using, but I see the do_IRQ in the stack trace multiple times. This brought some suspicious questions to me why so many times the module is interrupted. Ealier I was running with centos5.3 kernel, now running with centos5.5 kernel (2.6.18-194).
That is a _very_ old kernel release, please use something more modern. Anyway, this is a bug in the module you are using, there's not anything that preempt vs. non-preempt that is handling this. Please work with the company providing the code to fix the bug in their driver. greg k-h
