igc0 going offline w/default perfpolicy
Apologies-- thought I had updated this issue. Put a scope on the 13.5V
DC power supply and large transients are visible every 100ms when
setperf_auto() needlessly wakes all sleeping C6+ cores simultaneously.
ASRock likely took capacitor shortcuts and igc0/i226 can wedge if too
much power disruption. Frequent multi-core C6+ wakeup increase the odds
of an issue. (Modifying the setperf_auto() timer frequency changes the
time until failure.)
With respect to your questions and help future identification:
> What it you scenario? Do use this interface for a desktop with client traffic,
> for a Server which provice services like http, or as a router with forwarding?
This will be an edge server (WAN gateway, packet filtering, netflow analysis,
DNS/NTP/etc, certificate management, etc). I use DC-powered low-wattage boards
that are DC-UPS friendly due to outage issues at my locale (and WAN is only 1Gb
so don't need to go crazy).
This problem showed during initial OpenBSD 7.7 provisioning and thus never got
deployed. Have replicated with 7.2 and 7.8. (igc0/igc1 are on the same subnet
for ease of testing.)
