Dear Gleb,

Here is the info:
em0 at pci2:1:0:   class=0x020000 card=0x05491014 chip=0x101e8086 rev=0x03 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82540EP Gigabit Ethernet Controller (Mobile)'
    class    = network
    subclass = ethernet

I tried it, but the behaviour didn't change: immediate hang when
