During a kernel build the number of interrupts under 4.1R would typically peak at less than 150. Under 4.1.1 stable I am seeing peaks of 1200. Is this an artifact or did the 'ata' driver get changed? My hardware configuration (Dell Optiplex 200Mhz, 64MB) remains constant during the upgrade. I have performed the 4.1Release -> 4.1.1-Stable twice (this system is obviously not in production) and have observed the increased interrupt rate both times. Anybody got an explanation? Thanks.
