svc: bad direction 256, dropping request

[Mark Fraser]

Recently if I type dmesg in Konsole, I've seen the message
svc: bad direction 256, dropping request

repeated over and over again as in:

Is there any way of finding out what's causing it, I have a suspicion that it 
may be the RT61 driver I installed to get over the wireless networking 
problems I've been having with 7.10.
