I had a similar problem: it gave a kernel panic at random moments. Packages 
got corrupted and so on. I ran memtest86+ and it found that all of my memory 
was broken. So I recommend to check the memory as it was said above. if you 
happen to check the memory, please wait till test 7: it might give you most of 
the errors.
