Here's vmstat-i with Xorg running: interrupt total rate irq1: atkbd0 139 1 irq9: acpi0 835 7 irq12: psm0 1746 15 irq16: uhci3 20622511 177780 irq20: hpet0 uhci0 118696 1023 irq21: uhci1 11 0 irq23: ehci0 2 0 irq257: hdac0 3495 30 irq258: iwn0 13406 115 irq259: ahci0 8639 74 irq260: vgapci0 1979 17 Total 20771459 179064 And without Xorg running: interrupt total rate irq1: atkbd0 150 3 irq9: acpi0 378 9 irq20: hpet0 uhci0 8303 202 irq21: uhci1 11 0 irq23: ehci0 2 0 irq257: hdac0 61 1 irq258: iwn0 1536 37 irq259: ahci0 1634 39 Total 12075 294 So X is the problem? What can I do to fix it? Cheers, Peter Harrison.
