Hey all,

  I have a 9600, Sonnet 800mhz G4 card, 896MB RAM, Firewire/USB2 card, 
ATA/66 card, with an ATI Radeon 7000 for video, running Jaguar.

  Every once in a while, I get what I guess is a "kernel panic", where I 
get the Darwin terminal stuff all over the screen. This has happened 
twice now, and both times this has happened, it was pure hell getting 
the computer up and running again.

  The first time it happened, I was trying once again to at least get my 
IDE DVD drive to get along with the stock SCSI stuff. (I was never able 
to get the computer to boot with any IDE drives beyond the hard drive 
hooked up while the SCSI stuff was hooked up). This time around, I 
plugged the SCSI cable into the other SCSI port on the motherboard, and 
then plugged the DVD drive into the secondary IDE channel on the card. 
The computer got past the gray Apple screen, and got to the login 
screen, where I then got the kernel panic. Shutting down and 
restarting, I got no startup chime. After trying many things, the only 
way to at least get the startup chime back, was to open the case, pull 
the CPU card, press the CUDA switch, put it all back together, and go. 
Still wouldn't boot the first couple times, but it eventually did, sans 
the DVD drive. I also found during the ordeal that chances of getting 
the chime were higher if I'd unplug the machine, press the power button 
while unplugged, then plug it back in again. That was about a week ago.

  Then just today, I went to plug my external USB2 burner back in, after 
having unhooked it to take it to work the day before. I got the kernel 
panic. And then it was back to like it was last week, no startup chime. 
It was worse this time though, as I had to do the CUDA switch thing 
over and over and over again, to no avail. Sometimes I'd get the chime, 
but no boot. And simply pressing the CUDA switch wasn't enough; I had 
tried getting away with just pressing the switch without unfastening 
the top half of the case, undoing the IDE cable, etc.; It sort of 
demanded that I undo everything, else no startup chime. (I still don't 
understand that, as I don't think there's any sort of switch on the 
board that senses whether or not the top half of the case was opened.) 
But anyway, just grasping at straws, I moved the Firewire/USB2 card 
down a few slots on the PCI bus. Bang, it booted up, no problem.

  I'm not entirely convinced that moving the card had anything to do 
with the machine finally booting; I think it's just a coincidence. 
Anyone here have any insight on any of this?

Stace
