Hi I have a problem printing. The data rate through my parallel port to my printer makes the kernel think that lpt0 is storming at between 40k-49k irqs per second. Is there a way to tell the kernel to ignore certain interrupt sources or to raise the per-second throttle value? I've only found hw.intr_storm_threshold which I assume is the number of interrupts from a source before an interrupt arives from another source. I've set this to 2000 to make the printing work, but now I'm not sure if this will protect from a real interrupt storm. Ian -- Ian Freislich
