Bump the interrupt storm detection counter to 1000. My slow fileserver
gets a bogus irq storm detected when periodic daily kicks off at 3 am
and disconnects the disk. Change the print logic to print once per second
when the storm is occurring instead of only once. Otherwise, it appeared
that something else was causing the errors each night at 3 am since the
print only occurred the first time.
