Apologies, this is a qualitative post --- but now that people are talking
about different processors, I'll contribute some fluffy info.
That said, I experienced many "freezes" per day on my Core Solo laptop when
doing "dangerous" operations (svn update, rsync, rm, etc.). Then I swapped
to a Core 2 Duo, and when doing these same operations, I got about the same
number "freezes", only now they recovered faultlessly (so far...) after
second or two.
After an upgrade to 2.6.30-020630-generic #020630 from the Ubuntu Kernel-ppa
mainline, (to solve unrelated HP laptop sound issues), I have not
experienced any more "freezes" temporary, or otherwise.
