dmesg

em0: <Intel(R) PRO/1000 Network Connection Version - 3.2.18> port 0x8000-0x801f 
mem 0xf8020000-0xf803ffff,0xf8000000-0xf801ffff irq 17 at device 0.0 on pci3

Sometimes em0 or em1 was "freeze" with next messages in /var/log/messages(after "ifconfig <em_int> down && ifconfig <em_int> up" commands):
Oct 20 16:17:12 test kernel: em1: The EEPROM Checksum Is Not Valid
Oct 20 16:17:12 test kernel: em1: Unable to initialize the hardware

With lastest driver(6.1.4) from intel.com problem not solved.
