I have a odd situation where the according to top 50% of the processor is going towards interupt handling. vmstat -ai shows the nvidia device generating lots of interrupts. The interrupt issue goes away as soon as I kill X or switch to a terminal. X also slowly starts using up more and more CPU time. the schedule is 4BSD with preemption... none of the sysctl stuff for it has been changed... Any ideas? -------------- next part -------------- A non-text attachment was scrubbed...
