Rhine VT6102 problems

[Urban]

Hi, we have used VIA MS10000 mini-itx boards with the VT6102 network 
controller the last 6 moth with FreeBSD 5.4 great succeess. Now we 
received a new batch and now the network controller is not working 
properly (for all units). After changing the line in rc.conf to 
"vr0_ifconfg ... media 100baseTX" it works for one boot, but when 
rebooting again it will not work. When the network does not work there 
is 32 lines of ukphy0 to ukphy31 in dmesg and after that we also got 
vr0: watchdog timeout. I have searched the internet and there is 
reported problems about this in the past but there seems to be no real 
solution. We have tried different configuration with/without ACPI 
enabled, forcing the card to 10Mb and 100Mb, different switches without 
success. Is there any patches or solutions of this problem?

thanks
