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. >> gets very warm as everything (presumably) is running at full throttle. >> Is there any way to disable the ACPI partially, i.e. allow spin-down >> for disks etc, but keep the NICs running? > > This is IMHO not about FreeBSD support of ACPI but possible BIOS > settings that turn on some kind of hibernation. Each and every power saving function in the BIOS is disabled. Nevertheless, I believe that a selective ACPI configuration should resolve this issue, >> >> Hope that this question was understandable.
