everyone. I try to configure network adapter of my freebsd on virtualbox machine. At first setting up, I got it right. However, after a couple of reboots, my VM gives me a error message: says "em1:Watchdog timeout -- resetting"

I tried to google it, and there is no solution that works for me.

The following is my network adapter of my VM:

• Apapter1: NAT
• Adapter2: Host-only Adapter vboxnet0

On my Virtualbox setting: Host-only networks: Adapter:

• IPv4 address: 192.168.56.10
• IPv4 network mask: 255.255.255.0

On my FreeBSD VM /etc/rc.conf

• ifconfig_em0="DHCP"
• ifconfig_em1="inet 192.168.56.11 netmask 255.255.255.0"

Moreover, strange thing is that, for example, if timeout error message show at ttyv0 , when I log in at different ttyv[1-9], the error message will not be shown. but in ttyv0, it still gives me the message.

And, in term of functionality of em1, it does work.

I have no clue about this problem. Hoping any one can give me a solution or suggestion. That will be great! Thanks a lot.
