Interesting enough, I started having this same ages-old problem after a recent upgrade to 2.6.28-16-server kernel. The system performed without a single issue for three months before that, including under very heavy load. It runs Ubuntu Server 9.04 on dual-CPU Supermicro motherboard with Quad-Core AMD Opterons 2389 installed.
