See subj.
They appears to work for ~10 minutes then all hangs deadly. No one TCP 
service responds, but ICMP and UDP goes normally.
The machine is x86 Pentium 4 IPv4-only, IPv6 is turned off in every place.
Last kernel I have that works nice compiled at Mar 19.

Ethernet info:
fxp0: <Intel 82559 Pro/100 Ethernet> port 0xc000-0xc03f mem 
0xed100000-0xed100fff,0xed000000-0xed0fffff irq 11 at device 11.0 on pci1
miibus0: <MII bus> on fxp0
inphy0: <i82555 10/100 media interface> PHY 1 on miibus0
inphy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

This is remote machine, so I don't have console access.
