Linux hanged while receiving files via bluetooth
Hi, all

I tried to send and receive files by obex_test. It is success for sending. For Receiving :

I follows the steps from http://www.resultspk.net/hackwireles...-2-sect-7.html :

1)sdptool add --channel=<<OPUSH channcel of cellphone>> OPUSH
2)obex_test -b <<btaddress of cellphone>> <<OPUSH channcel of cellphone>>
3) s (for server mode)

then I send file from cellphone. After a while, Linux machine is hanged, need to reset.

the followings are captured from hcidump :
