>Description:
This is my box hardware:

Abit Aw8d + PentiumD930 +1 G ram

The pciconf -lv output about the re hardware :

rl0 at pci3:0:0:   class=0x020000 card=0x240b147b chip=0x816810ec rev=0x01 hdr=0x00
    vendor   = 'Realtek Semiconductor'
    class    = network
    subclass = ethernet
rl1 at pci4:0:0:   class=0x020000 card=0x240b147b chip=0x816810ec rev=0x01 hdr=0x00
    vendor   = 'Realtek Semiconductor'
    class    = network
    subclass = ethernet


When I use the default if_re driver for this hardware , I often get the 
"Nov 27 19:41:37  kernel: re1: watchdog timeout
Nov 27 19:49:13  kernel: re1: watchdog timeout
Nov 27 19:49:20  kernel: re1: watchdog timeout
Nov 27 19:49:28  kernel: re1: watchdog timeout
Nov 27 19:52:28  kernel: re1: watchdog timeout
Nov 27 23:37:09  kernel: re1: watchdog timeout
Nov 28 01:03:19  kernel: re1: watchdog timeout
Nov 28 01:21:08  kernel: re1: watchdog timeout
Nov 28 01:24:45  kernel: re1: watchdog timeout
Nov 28 01:27:22  kernel: re1: watchdog timeout"

And Network is down.
I think That should be fixed.
>How-To-Repeat:
Use the default driver , then will get the output and the network will down.
>Fix:
Use The Realtek.com's driver for freebsd will slove the problem.
