Hm seems my last mail got lost and didn't reach the mail list.

I replaced the broadcom device with other intel gigabit card:
em1: <Intel(R) PRO/1000 Network Connection Version - 6.5.2> port 
0x2000-0x201f mem 0xb8c00000-0xb8c1ffff,0xb8400000-0xb87fffff irq 19 at 
device 0.1 on pci4
em1: Ethernet address: 00:15:17:1b:08:ed
em1: [FILTER]

on the other end is the "problematic" network card (that does work under 
linux&windows):
em0: <Intel(R) PRO/1000 Network Connection Version - 6.5.2> port 
0x2000-0x201f mem 0xf0500000-0xf051ffff,0xf0524000-0xf0524fff irq 19 at
 device 25.0 on pci0
em0: Reserved 0x20000 bytes for rid 0x10 type 3 at 0xf0500000
em0: attempting to allocate 1 MSI vectors (1 supported)
msi: routing MSI IRQ 256 to vector 49
em0: using IRQ 256 for MSI
em0: Reserved 0x1000 bytes for rid 0x14 type 3 at 0xf0524000
em0: bpf attached
em0: Ethernet address: 00:0f:fe:4e:78:16
em0: [FILTER]

When I verbose boot the server I see:
em0: Link is up 1000 Mbps Full Duplex
em0: link state changed to UP
em0: Link is Down
em0: link state changed to DOWN
em0: Link is up 100 Mbps Full Duplex
em0: link state changed to UP

if I type ifconfig em0 media auto it happens exactly the same:
card down
card negotiate to 1000 Mbps Full Duplex
card up  - netowrk work for 2 seconds
card down
card negotiate to 100Mbps Full Duplex
card up.

If i force 1000mbps network :
ifconfig em0 media 1000basetx mediaopt full-duplex
2 seconds latter I see: status: no carrier

Both machines are running FreeBSD 7.0-CURRENT from ~2 days ago.

A checked up connection between bge0 and the new server with intel card 
and everything works fine.
