Hi,

did anybody test Routerboard 44? It is quad network card, uses VT6105M chips 
as network controller (Via) and PCI6152 as PCI-PCI bridge (PLX Technology). 
With both stock if_vr and modified from site given above it partially works - 
interfaces are created, ifconfig works, but even pinging some host in local 
network (I achieve the effect with ping -f in a minue or so) hangs system. 
Nothing on my console, nothing in system log. Only hard powerdown restores 
system in functioning state.

I tested it with stock vr driver in both 6 and 7 stable on both i386 and 
amd64, and now with overhauled vr in 8 freshly cvsupped and two files 
replaced on i386.

If anybody has any idea or some patches I could test, I will.

Regards,
Milan
