Wild guess: weak power supplies? AMD chips are heavy power users, and
want clean power. We had a small AMD K6 cluster that exhibited instability
for quite a while before being decommisioned. A few months back one of the
former nodes blew a power supply, was replaced with a different brand, and
all instabilities vanished. The next cluster is getting higher grade
