Kernel panic!

[Carolus]

Questa mattina all'avvio il mio Mac Pro all'accensione ha caricato la mela grigia, è apparsa la rotellina grigia e poi è rimasto piantato alla schermata grigia. Al riavvio mi è apparso un messaggio indicante un Kernel Panic che recita così:

Sun Feb 6 12:06:47 2011

panic(cpu 6 caller 0xffffff8000226822): "Spinlock acquisition timed out: lock=0xffffff800067d920, lock owner thread=0xffffff801d0af000, current_thread: 0xffffff801ce3c620"@/SourceCache/xnu/xnu-1504.9.26/osfmk/i386/locks_i386.c:346
