Hi All,

While running stress-ng on my Quadra 630, I observed a reproducible panic 
in do_exit():

        if (unlikely(in_interrupt()))
                panic("Aiee, killing interrupt handler!");

The console log says,

running --mmap -1 --mmap-odirect --mmap-bytes 100% -t 60 --timestamp --no-rand-seed --times
stress-ng: 22:22:17.70 info:  [19803] setting to a 60 second run per stressor

I haven't found the cause yet. While investigating I tried enabling 
various debug options including CONFIG_DEBUG_SPINLOCK. I then got 
backtrace below from the same machine.

Apparently add_interrupt_randomness() got re-entered, causing 
spin_trylock() to contest input_pool.lock. But I don't see anything wrong 
there -- false positive?

I was able to reproduce that on both QEMU and Aranym:
