Weird ISR accounting in 10-STABLE

[Vlad Galu]

Hi John, thanks for reaching back. Yes, that must have been it, although
the machine was completely idle at the time, except for my SSH session it
was not generating or receiving any other traffic.

I have since updated to r267702 and the problem seems to have magically
disappeared... I still have the old kernel but can't currently reboot the
machine. When I do next, I will revert to it and try to provide more
information.
