[Voyage-linux] ifdown/ifup on ath0 causes WRAP to reboot

[Edwin Whitelaw]

WRAP2C with 0.2 voyage + apt-get upgrade using default sources.list 
file.  Tried SR5, CM9 and EMP8602 radios with identical results.  Also 
switched WRAP boards with no change.

If I run ifdown ath0 followed by ifup ath0 the system always reboots.

Anyone have any thoughts on why this is happening?  I have other boards 
that dont' exhibit this behavior.

Thx,

Edwin

Comment:  using "wireless-txpower 26db" does *not* work while "up 
iwconfig ath0 txpower 26db" does.  ???
