I had similar issues on an Athlon machine under 5.3. In my case it turned
out that the CPU was running extremely hot. It would frequently freeze
while portupgrade was backing up old versions of a port. I initially
suspected a disk problem as well, but I haven't yet had any problems since
cleaning my CPU and chipset fans. On reflection, my freezes were probably
due to the CPU running hotter than usual when running bzip2 (which I
believe is how portupgrade stores its backups, and is very CPU-intensive).
It is possible that your drive is the culprit, but you would probably get
console messages about I/O failures rather than just a hard freeze.
Flaky memory or power supply are also possibilities.
