Hi, I have a PM 7500 with the Sonnet g4 800 600+ ram, suddenly yesterday my mouse froze, than I tried to reboot and the reboot took about 45 mins in to OSX.2.4, SO I tried to boot to OS9 and it booted but a little slower than usual. I checked the Metronome Sonnet software in os9, and it says the processor is running fine and the l2 and L3 caches show up properly. SO i tried to boot to another HD with OSX.2.4 on and it booted Extremely slow n fact it took overnight. Watching the boot process in verbose mode evrything looks normal except the messages AppleMacRiscVCI: bad range..... three times and like I said it is very slow. It seems the processor is running at 10% normal, is this possible? What else could it be?? Thanks Steve Okinawa |

Joevt Thanks for the reply. I figured out what it was. A mouse which may have gotten some Coke on it. Because the first thing I noticed was the mouse freezing I decided to pull the USB/FW PCI add in card that the mouse was connected to. Then I rebooted and all was fine. Then I put the card back in without the mouse and all was still fine. But when I attached the mouse, the mouse did not work and I got the extremely slow reboot. I surmise becasue the Video card ia also a PCI card (radeon) that the error messages were related to the signal getting corrupted from the mouse on one PCI bus to the other PCi bus or something like that. I find it very interesting that it made it seem as though the processor was running at 10% (or less) and that the performance under OS9 wasn't all that different. If I hadn't noticed the mouse freezing first I may still be trying to figure this out. But it goes to show the troubleshooting technique of pulling peripherals one at a time has a lot of merit. I would never have guessed from the symptoms that a Coked up mouse was the problem :) Steve Okinawa |

Was there a particular place in the bootup process where the slow down occured or was every step slow? What software are you using to enable the L2 and L3 cache in OS X? Those AppleMacRiscVCI messages have something to do with the video PCI bridge called "/chaos" where the built in monitor output "control" and video input "planb" are located in the device-tree. They are normal (by that I mean that any Mac with a VCI bus -7500, 8500, 8600- will get those messages; I can't say whether or not those messages mean that the AppleMacRiscVCI driver is not behaving as intended). |
