I had somewhat similar problems (but only on shutdown) when I upgraded my G3/250 WS running OS 8.1 to G4/500 (Sonnet upgrade card, upgrading to 9.1 at the same time).
It took about eight months (!) to diagnose the problem (with the help of a Mac expert via e-mail). It seems to have been an extension conflict with the Iomega extension. Just putting a tilde (~) before it solved the problem -- G-Books is sponsored by <http://lowendmac.com/> and...
