Did you ever run Linux on old (pre-ATX) machines? It's the same as with not having the apm or acpi drivers loaded ... "shutdown -h now" kills all processes, but not the kernel itself. The kernel still runs until the power is off. My 80386 router died some weeks before I decommissioned it. The real reason I did so was to make more efficient use of limited electrical outlets. I think the init(8) crashed because of a hard drive failure, but the box continued passing packets in perfect form. -- mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header |
