Firstly, what is a PC164SX? (The headers suggest that it is some kind of Alpha). Can you put the 'device random' back in, and try turning off entropy harvesting by turning off each of the following sysctls to see if any of them "fix" the problem? kern.random.sys.harvest.ethernet kern.random.sys.harvest.point_to_point kern.random.sys.harvest.interrupt I am suspecting that a high-rate interrupt is being harvested, and that this is the problem. Also, please run 'systat 2 -vmstat' for a while, and stare at the irqs (top-right-ish) and see if any/which of them are high-rate interrupt sources, and let me know which. Is it possible to get an account on this box? Thanks!
