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. JN
