Hello, all.

I'm trying to use Hokuyo laser scanner(URG-04LX) on gumstix.

Although successfully built hokuyo_node package, alignment exception fault

but getID and getFirmwareVersion worked find.
Device at /dev/ttyACM0 has ID H0907156
Device at /dev/ttyACM0 has FW rev 3.3.00(16/Apr./2008)

hokuyo_node produced this kernel error message.

Alignment trap: not handling instruction ed868b00 at [<0002f6be>]
Unhandled fault: alignment exception (0x801) at 0x000875bb
/opt/ros/cturtle/ros/bin/rosrun: line 35:   729 Illegal instruction    
$exepath "$@

Does anyone who experience this kind of error or know how to handle it?

Please let me know.

Many thanks in advance.
