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?
See this: http://madwifi.org/wiki/UserDocs/WRAP
Also note that the problem occurred with a single CM9 or a single
EMP8602, neither of which should challenge the power supply.
Can you comment on why I had to use the "up iwconfig..." to set power
instead of the "wireless-tspower" option?
Thx,

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. ???
