I set up tcpdump on my router to listen and confirmed it's working by booting the machine in question into linux and seeing a DHCP request arrive at the router. I also confirmed I can reach the WAN just fine. When I then tried to boot into ipxe, I started getting link down errors (http://ipxe.org/err/380861). This was the first time I've encountered this. I also noted that the debug message for unexpected ICR showed 00000102 instead of 00000106. This persisted across a few soft shutdowns so I pulled the power completely and let it sit for a bit. At next boot, we were back to the same messages I sent in my previous email. Tcpdump on my router indeed shows 4 DHCP requests, but ipxe still ends with "No configuration methods succeeded / No more network devices". It then drops out two more debug messages about forced MAC resets before output stops. I checked logs on my dhcp service and see it responding with an offer to each of the 4 discoveries but there are no requests coming back after the offers.
