Hi all My ethernet driver for a pc card's output packet function fails, whenever i try to move data from the mbuf structure

for(mn = pkt;mn;mbuf_next(mn)) { //bcopy(mbuf_data(mn)), des_ptr_ub, mbuf_len(mn)); des_ptr_ub += mbuf_len(mn); } the bcopy fails and creates a kernel panic . any reasons???

You have an infinate loop, and are writing past the end of des_ptr_ub. (hint: you are forgetting to assign mn = mbuf_next(mn)) Drew _______________________________________________ Do not post admin requests to the list. They will be ignored.
