I have compiled the Bluez Utils and Libs 2.11 for a ARM platform, concretly for the CPU ARM7TDMI.
I have done the compilation with uClibc-0.9.19 and in "hciconfig" tool I have a problem when I make"hciconfig -a" or "hciconfig hci0 name" or "hciconfig hci0 class" and other.
All this problems occurs in file "hci.c", in function "int hci_send_req(int dd, struct hci_request *r, int to)".
In this function when the program execute "n = poll(&p, 1, to)" I obtain a kernel panic like this (executing hciconfig -a):
