OK let's see what can I provide:

CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 6000+ (2999.98-MHz K8-class CPU)
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
usable memory = 8543711232 (8147 MB)
avail memory  = 8264265728 (7881 MB)

Also:

        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active

Other machine, same configuration besides:

re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM>
        ether 00:19:db:f8:c9:48

        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active

There is another one, which is suffering this problem.

I have the same hardware configuration on yet another one, but it
doesn't seem like to have these symtons, which is interesting:

If you are interested in any other information, just ask me and I will
provide it.
