But I think that you would have to install the complete CVS repository to generate such a changelog. Besides, if you are not a programmer, would the checkin comments really mean anything to you? > 29 ?? WL 1:35.00 [irq19: skc0 atapci2] It looks like one of your disk controllers is sharing an interrupt with another device (network card? can't find a skc device, only sk). That might have something to do with your problem. Try disabling that device, and see if your troubles disappear. If so, you could try to add a device hint to have the skc device use another free interrupt line. See device.hints(5).
