[ipxe-devel] iPXE 1.0.0+ fails to load linux kernel, sends ARP requests

Hello!

My name is mr Jussi Peltonen. I have been using successfully PXE for
several years with different kinds of hardware.

Now I have run into a problem with iPXE on Intel 82571EB. For some unknown
reason loading of Linux kernel fails. I think that 7 boots out of 10 fail.
I have captured network traffic with Netshark. Captures show, that when
kernel load fails, network adapter starts to send ARP requests to find the
server.

Interesting frames are included at the end of this message.

Capture files can be downloaded from my personal web page:

http://personal.inet.fi/koti/juho69/boot_ok.pcap
http://personal.inet.fi/koti/juho69/boot_failed.pcap

Can you find reason for this kind of behaviour?

Please, help.

Best Regards,
Jussi Peltonen
