Kernel Panic (CPU 0): Unresponsive processor

Hi all,

I've bought three weeks ago a refurbished iMac (it is the last version before the new thin model).

I frequently (once every one/two days) have kernel panics. Todays I tried to read the report, which I report below.

Can someone help me in undesrsandig end possibly solving the prosblem?

Thank in advance,

Luca
