Just noticed in dmesg after reboot:

vr0: Tx underrun -- increasing Tx threshold(128 -> 256)
vr0: Tx underrun -- increasing Tx threshold(256 -> 512)
vr0: Tx underrun -- increasing Tx threshold(512 -> 1024)
vr0: Tx underrun -- using store and forward mode
vr0: Tx underrun --

at this moment I started copying files in and out using samba
and then last message started to repeat for some time with decreasing 
frequency until finally:

vr0: watchdog timeout

and no more errors were reported.

Despite the errors in dmesg everything seems to work fine at all times 
with samba tx performance of 9.5mb/s and rx of 8.5mb/s using Vista as a 
client.
