Bug 96284

I have a Intel motherboard Intel Server Board SE7230NH1-E (LX Version)
(http://www.intel.com/design/servers/boards/se7230nh1-e/index.htm). It
contains two ethernet cards, Intel Pro/1000. 

I installed the FreeBSD without any problems. But! Then I try to bring on
ANY,SECOND, of those interfaces, the computer hang off immediately. For
example - if I have "em0" bring on, I can't to bring on "em1", and vice versa.
There are not any messages on console, ther are no messages in logs, nothing.
I tried to change kernel from GENERIC to my custom. Problem did again. I
tried to cvsup my "world" to RELENG_6_0_0_RELEASE and made world after.
No progress,  the system hung again. I tried to set debug.mpsafenet to 0.
Hung again...
