Sorry for the increase in traffic. I just wanted to add a bit of extra information.

I stopped called dhcp_fine_tmr() and dhcp_coarse_tmr() to see what effect that would have, and now dhcp_start() and dhcp_stop() return as expected. dhcp_start() will not make multiple calls to dhcp_discover() in this state, but since I can restart the process manually that isn't a huge problem.

I would still like to know what the problem is, if anyone has any ideas.

Does anyone know what could cause dhcp_start() and dhcp_stop() to never to return?

I can call dhcp_start() once, and if I get an offer immediately everything is fine. However, I only send one discover message. If I don't get a reply to that message nothing more happens.

I've tried calling dhcp_stop() (after a timeout) so that I can restart the transaction, but dhcp_stop() never returns. I've tried calling dhcp_start() again without stopping it first but the second call to dhcp_start never returns.

Does anyone have any idea why this might occur?
