For what its worth I have problems with one em based interface as well, 
it locks the machine solid when used:

em0: <Intel(R) PRO/1000 Network Connection, Version - 1.7.25> port 
0xb000-0xb01f mem 0xfb100000-0xfb11ffff irq 10 at device 1.0 on pci1
em0: Reserved 0x20000 bytes for rid 0x10 type 3 at 0xfb100000
em0: Reserved 0x20 bytes for rid 0x18 type 4 at 0xb000
em0: [GIANT-LOCKED]
em0: Ethernet address: 00:30:48:80:9f:b6

where this one works just fine:

em1: <Intel(R) PRO/1000 Network Connection, Version - 1.7.25> port 
0xa800-0xa83f mem 0xfa000000-0xfa01ffff irq 19 at device 10.0 on pci3
em1: Reserved 0x20000 bytes for rid 0x10 type 3 at 0xfa000000
em1: Reserved 0x40 bytes for rid 0x18 type 4 at 0xa800
em1: [GIANT-LOCKED]
em1: Ethernet address: 00:30:48:80:9f:b7


The chips are these
em0_at_pci1:1:0:   class=0x020000 card=0x10758086 chip=0x10758086 rev=0x00 
hdr=0x00
em1_at_pci3:10:0:  class=0x020000 card=0x10768086 chip=0x10768086 rev=0x00 
hdr=0x00
