Macbook Random Shutdown

Hello everybody,
I did not know that this blog is for MacBook Pro Users also

I bought a MacBook Pro 17 inch 2,16 GHZ 2GB RAM in May here in Germany. Since then I had to fight with Kernel Panic for instance like this (different crash logs possible):

panic(cpu 1 caller 0×0019CADF): Unresolved kernel trap (CPU 1, Type 14=page fault), registers:
CR0: 0×80010033, CR2: 0×8fe29004, CR3: 0×00d9f000, CR4: 0×000006a0

Before i had a Powerbook G4 17 inch 1GHZ 1 GB RAM and never had any problems with it (even did not know that kernel panic exists).

I formatted the HD and installed the system for several times. I tried to fix some software problems after loooking at the “Konsole” with my migrated data.

The MacBook Pro had been to the local dealer where I bought it in Hamburg three times. They changed: 1. Processor, 2. Logicboard (is there a difference?) 3. Body (just to give me the chance to change the complete MacBook for a new one)

When I was on a “holiday trip” I started from an external LaCie HD and it crashed totally. I could not start from the intern HD again. I went to a local Mac-Dealer, who checked the RAM (no problem), then left me with the info: Apple Service.

So I went back home, the local MacDealer saved my data from HD and the 2nd and 3rd repair as mentioned above followed.

Kernel Panic did not stop.

For 1 day now it worked fine, before it crashed approximately twice a day. I am working on a keynote presentation which I will show In October to an audience of 1000 people. I really have panic that there will be kernel panic again and I loose this job forever.

I read some messages that Apple will bring out a revision of either MacBook Pro 17 or logicboard for it, so I am waiting still to change it.

Does somebody have the same problems or knows something about new logicboard or MacBook Pro 17?

Thanks
Bernd
