[CUBE] PM G4 Cube - Upgrade or not!?

[Luis Meleiro]

Listers,

I've finally upgraded my Cube with a PL 1,35GHz but I'm facing occasional erratic behaviour in the Mac.
I've 'religiously' followed the Video CD included by PL and I'm positive I've done it as PL indicates.

My computer boots, works, but gives me occasional crashes/kernel panics each time I open Apple Disk Utility or Apple System Profiler. This happens everytime I choose ATA or FireWire options. It seems the machine isn't able to find/list ATA or FireWire connections. This is not persistant though, sometimes I boot and open the same apps and everything just goes smooth... it recognises my internal 80Gb ATA hdd and my external 160Gb FW hdd.

I've tried archive and install from Panther CDs but it can't install the system in my internal hdd. Nevertheless, I've accomplished a perfect Panther installation in my external hdd.

I've reseated everything from the beginning and checked for bad cable connections/contacts. Didn't find anything wrong.

Does everyone here who recently installed faced these or similar issues?
What shall I do to understand/nail what might be happening?

Please help/advise. Thanks in advance,
LM
