right, I have attached picture of the kernel messages displayed when the
machine crashes. I hope this helps.

Yes, I understand why that information would be very helpful.
Unfortunately, I don't know exactly when these errors began to occur. I
cannot easily find out either, because these kernel panics more or less
randomly -- I don't know how to trigger such the event. Sometimes, the
machine works just fine for a day or two, and then it crashes 4 or 5
times in a row for no apparent reason. I'm sorry for not being any more
specific, but I just don't know more.

Take care,
Peter
