Bluddy Kernel Fault

[steveimp]

Now then, my IBook (G4 bought last year) has started to kernel fault. No new software or hardware added since the day it was purchased. On reboot, the OS loads up and it kernel faults again straight away. The one time it has managed to stay stable long enough is for me to able to read the report and it says something about the passwords and keychain. I don't log into the machine at the beginning as in through the multi-user route it just loads straight to desktop, so I'm concerned as to whats going on here.....


On one reboot, it went to a white UNIX type screen and asked me to type mac-boot or shut-down.

Very weird goings on here, any ideas guys?

Have you tired sticking in your system disc and repairing permission?

Yep and I've run the hardware tests - no problems in either.

Now the kernel panics start straight after boot up!

Been through this:

?

Of particular interest should be booting in Safe Mode. Do you have 3rd party RAM in there or is it all Apple?

When it becomes an issue with the machine going straight to a Kernel Panic it usually indicates something is very wrong and quite likely hardware related.

The white screen you had pop up is Open-Firmware which is pretty much the same as BIOS in a Windows environment. You can easily bring this up by holding down cmd-opt-O-F on startup . Once you are in Open-Firmware you can then issue a couple of commands which may possibly help if the kernel panic is in software:

The two commands are:
nvram-reset
reset-all

What these commands will do is reset all your Open Firmware settings which may potentially be corrupt.

The knowledgebase article yellow mentioned will also be helpful.
