When the server is idle with ACPI enabled, it did not respond to ping 
after a short period. With ACPI disabled, this was alleviated. So, 
basically, it will stop working after a while. My guess is that ACPI 
will shut down the power for the NIC. But that is only a guess. 
Furthermore, when ACPI is disabled, no network problem arises. This 
suggests, at least to me, that ACPI is somehow involved.

Each and every power saving function in the BIOS is disabled. 
Nevertheless, I believe that a selective ACPI configuration should 
resolve this issue,
