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

[Kim-man "Punky" TSE]

Hi Edwin,

Tried you config and does exhibit your reboot problem.  Do you see 
kernel panic message in the serial console?  If not, I think it is 
probably relates to power issues.  Check your PSU unit, or check your 
WRAP board if it has 8 capacitors?
