[Voyage-linux] ksoftirqd/0 consumes all CPU during atheros transmit

[Edwin Whitelaw]

Downgrading to Voyage 0.4.1 does eliminate the problem.  Obviously this 
is not a long term solution.  I had posted earlier that 0.6.1 
demonstrated a nasty habit of inexplicably dropping all communication 
with client systems so have had to stay with 0.5.2 and now have the 
ksoftirqd issue.
