   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
cases/power supplies.
