Kernel panic

[grafosiculo]

Ciao a tutti, il mio fido iMac G5 comincia a fare bizze, ultimamente è andato per ben 3 volte in Kernel Panic, restituendomi il seguente messaggio (che io non so interpretare) secondo voi da cosa può dipendere?

Ecco il resocoonto:

Sembra che il problema sia dovuto ad un USB cosa hai collegato?

Non sono molto esperto ma da quello che leggo mi sembra cosi..

[grafosiculo]

Ho collegato un masterizzatore Lacie ed una stampante Canon (da un paio d'anni) ma anche un mighty mouse (o come cavolo di scrive), poi niente di anomalo.

Ciao e grazie
