Hardware:
IBM T43 (Gigabit Ethernet)
Plugable USB 2.0 to 10/100/1000 Gigabit Ethernet LAN (ASIX AX88178 Chipset)
Loaded pfSense onto the laptop's hard drive. Using internal NIC on WAN side and USB NIC on LAN side.
Works very well but I would like to use powerd to throttle the CPU. I don't need it running at 1.6GHz all the time. Increases the heat output which is noticeable when touching the area around the laptop where heat is exhausted. When powerd is enabled, that area is much cooler to touch.
The problem.
The above configuration with powerd off and computer lid closed works fine. 4 days running, no problems. Once powerd is enabled, everything seems fine until I close the computer lid. After a few minutes the USB NIC stops working. The link light is still green, activity light occasionally flickers, very infrequently, but there is no network traffic passing through that interface.
Initially I thought the USB NIC adapter was faulty. But I just noticed that, when powerd is enabled, if the lid is open, network traffic was flowing without problems for little over an hour (testing period), when I close the lid, within few minutes network traffic on that interface stops. The only way I know off to bring the USB NIC back online is to reconnect it and have the system reinitialize it.
I'm not familiar with Unix/FreeBSD. Are there maybe some settings somewhere that I can change to prevent this situation? Prevent powerd from stopping/disabling the USB NIC when the lid is closed? I saw something about lid_... in configuration variables but it's set to NONE, so I don't think it is the solution.
Thanks.
