I'm preparing a G4 as in the title for my wife, who currently uses an eMac/1GHz, so that she can use an ADC Cinema Display HD (23") with it. Erase and install (using a SuperDuper! sparsedisk image from her principal volume on the eMac) went with the usual ease from SuperDuper! Subsequently, however, each reboot of the 100GB partition (10.4.11 with all system updates as far as SecUpd2008-007) has produced the message that AudioIPCDriver.kext was improperly installed and cannot be used.
Straight replacement from a known-good copy is not possible because the gods in the machine do not allow modification of the active System folder, but pre-erasure of the existing file during the attempt to copy produces consistent KPs from which there is no escape. Whether the extension does something useful or is just Tiger's security blanket doesn't matter; KP is certain, inevitable and immutable. So I booted the DA from an external FireWire drive (so that the misbehaving installation was now part of an Ignore ownership on this volume setup, erased the misbehaving .kext and copied in a good one. The affected volume then returned to booting the DA normally, but displaying the message about improper installation again as soon as the Desktop was reached. Evidence that summat is amiss is given by the absence of the .kext from the list in System Profiler/Extensions.
I had previously prepared a base set of upgrades and SecUpdates for just such occasions as this, or for new installations from scratch, but before I go to the pain of a clean installation and update of 10.4 again—so as to preserve applications, documents, user &c.—are there any ideas about disciplining this pesky .kext? Repairing permissions, rebuilding the File Directory with DiskWarrior 3.0.3 and forcing universal prebinding from Pacifist has not worked, so are there any other guesses as to the cause of the 'improper installation', with or without solutions of the problem?
All informed and plausible speculations are welcome.
