Just like the title, I have a G4 sawtooth with a sonnet 1.2Ghz upgrade card, 1.5 GB ram running TIGER (all updateds)
Now lately all of a sudden I keep getting kernel panics...nothing has been changed, no upgrade hardware, the machine has been running fine for over 4 years no issues...now all of a sudden kernel panics.
the only thing that was recently done was hooking up a telephone line to the modem for faxing - that's it.
So when I try to boot from diskwarrior, using the system preference start up disk section nothing happens. I click on the diskwarrior disk and hit restart and NOTHING!
I even restart holding the C button down and NOTHING.
But when I have no issue booting from Tiger DVD.
Just wondering if anyone else has had Kernel panic issues lately.
When Hell is full, the dead will walk the earth.
I had that exact problem with my Sawtooth.......unfortunately the news is not good.
Upgraded the 450 MHz Sawtooth with a OWC 1.4 GHz CPU upgrade several years ago. Everything ran fine for those years and suddenly, out of the blue, Kernel panics which I had never ever seen before.
After a lot of testing, it eventually turned out that the G4 upgrade CPU itself was the problem. Can't remember what tests OWC suggested, but they definitely pointed to the CPU.
I was lucky - the CPU had a three year warranty and the Kernel panics started a week before the warranty was up.
I shipped the CPU back to OWC, they replaced it with a new one under warranty - this was about six months ago. No problem since.
Talk to Sonnet - it may be the CPU. They should be able to tell you how to test it.
