This didn't help either, but finally I found a solution. The server worked fine for a while; the only difference was that I used a PCI ATA controller at that time. So I thought that it must have something to do with the system BIOS or the onboard ATA controller. In a discussion forum someone gave the hint to change the hard disk drive settings in the BIOS setup from "Auto" to a user defined value. I can't really understand why FreeBSD with SMPng stumble on this, but surprisingly it seems like that it works now. It must be a weird BIOS or hardware bug. Many thanks for your assistance.
