Two problems about ASUS N3150I-C

Hello.

I have two 11.1-RELEASE amd64 boxes working as my home servers. Their
hardware spec are same and ASUS N3150I-C is used as motherboad. And
there are two problems about it.

1. 'shutdown -r now' doesn't work after system has been up for a while

If I try 'shutdown -r now' just after system is up or after few hours,
it works as is expected. But, for example, if I try it after one week
of uptime, then it doesn't work anymore. OS is shutdown successfully
but reset never happens. I updated BIOS of motherboard to latest one
but it didn't fix the problem. And this problem happens on both boxes.

2. NIC gets no response with 're0: watchdog timeout' kernel message

Realtek RTL8111H is used as NIC of this motherboad. Sometime it gets
no response after following kernel messages are displayed some times.

Dec 10 01:11:37 maybe kernel: re0: watchdog timeout
Dec 10 01:11:37 maybe kernel: re0: link state changed to DOWN
Dec 10 01:11:41 maybe kernel: re0: link state changed to UP

If this happens system need to be rebooted. It is very variable when
NIC get this status. Sometime it happens after few hours system is up,
but sometimes it doesn't happen after a month of uptime. And this
problem happens only one of two boxes. One box is used for internal
services and the other is used for external ones. The problem only
happens on the latter. As is explaind above they have same hardware
spec, but OS settings and/or installed applications are differnt. So
it seems some of them specific to the latter are cause of NIC hangup.

Then, are there any way to fix these problems or investigate why they
happens? Any suggestions or comments are welcome.
