It's odd, but I'm inclined to disbelieve that it is either a hardware or an OS problem (in the sense that it is not specifically because of a bug in the OS)... more likely it is glitched data or a bad OS install (upgraded upon bad files).
I upgraded my 12" PowerBook G4 (867 w/ 640 MB and Combo Drive) from 10.2.6 to 10.2.8 with no problems. First I logged into single user mode (command+s at reboot) and ran fsck -y from the prompt, rebooted, and then ran Disk Utility to fix permissions right before installing 10.2.8 to make sure that it had all stable 10.2.6 files to install over. Did you take those precautions first or simply install it? Apple doesn't tell you to, but it's been I don't know how many times on MacFixIt that computers where these two things were done first generally don't suffer abnormalities after the install of an OS upgrade..save weird driver conflicts.
Now, back on track to fixing yours, have you tried the mother of all resets?? Deeper in the computer in the Open Firmware.... Do this carefully...
1. Reboot into Open-Firmware mode
(
http://docs.info.apple.com/article.html?artnum=24605)
Hold command+option+O+F in reboot.
2. You will see the Open Firmware prompt which looks like this:
Code:
Apple PowerBook6,1 4.5.5f4 BootROM build on 01/14/03 at 13:44:26
Copyright 1994-2003 Apple Computer, Inc.
Welcome to Open Firmware, the system time and date is: xx:xx:xx xx/xx/xxxx
To continue booting, type "mac-boot" and press return.
To shut down, type "shut-down" and press return.
ok
0 > _
3. Now to reset the Open Firmware...
(
Reset procedure for Open Firmware outlined in knowledge base article 42642)
Code:
1. At the Open Firmware prompt, type: reset-nvram
2. Press Return.
3. At the Open Firmware prompt, type: reset-all
4. Press Return.
Example:
0 > reset-nvram
Press Return
0 > reset-all
Press Return
The reset-all command should cause the computer to restart.
If this occurs, you have successfully reset the Open Firmware settings.
If for any weird reason this doesn't happen, and you get another 0> prompt, try typing bye, shut-down or mac-boot to get out of Open Firmware then contact Apple about your defective firmware.. ;)
Word to the wise:
- Don't do anything else in open firmware mode other than specifically those directions unless you really know what you are doing..
... If THAT doesn't work, try running all the Unix maintenance scripts and deleting all the user and system caches (including swap file) with a utility like Onyx (free) or Cocktail or Jaguar Cache Cleaner.. in conjuntion with fixing permissions, then another reset with resetting PRAM...
! Don't forget that resetting the NVRAM or PRAM will reset most of your settings in system preferences as far as time/date/networking/startup options for volume, brightness, and startup disk etc..
Be sure to fix your system date before you run any disk repair or file-altering utiltiies like fix-permissions.. as a precaution against bad dates on files.
... If THAT doesn't work.. then I would recommend reinstalling 'clean' from your highest Jaguar disk (10.2.7?) and doing the "combo updater" version of 10.2.8 when it becomes available again. For some reason, the combo updaters seem to have fewer problems than the sequential updaters.
