[ipxe-devel] DHCP problems on Intel 82567LM

I have similar symptoms, very reproducible.

same nic, but in an HP laptop:
lspci.. 00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit
Network Connection

apt-get install grub-ipxe
342468 Jan  6 03:59 ipxe.lkrn

update it:

vt at pc9d:/boot$ sudo wget  http://boot.ipxe.org/ipxe.lkrn
2014-05-02 17:24:01 (188 KB/s) - ‘ipxe.lkrn’ saved [369882/369882]
vt at pc9d:/boot$ ls -l ipxe.lkrn
-rw-r--r-- 1 root root 369882 May  2 17:00 ipxe.lkrn
vt at pc9d:/boot$ md5sum ipxe.lkrn
ca7c8c447041b40c1d65e34fbf6d0346  ipxe.lkrn

reboot

grub menu, pick ipxe,
iPXE 1.0.0+ (c6474)
 see dhcp/tftp traffic, repeat a few time just to be sure all is good.
Nothing seems to be wrong.

reboot.

grab the ubuntu net installer:

 wget -N
http://archive.ubuntu.com/ubuntu/dists/trusty/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/linux
wget -N
http://archive.ubuntu.com/ubuntu/dists/trusty/main/installer-amd64/current/images/netboot/ubuntu-installer/amd64/initrd.gz

pxe boot :
        linux ubuntu/trusty/amd64/linux
        append initrd=ubuntu/trusty/amd64/initrd.gz root=/dev/rd/0 rw

Enter though the defaults about keyboards and such, get to networking:
"Configuring network with dhcp... " error.

At this point, nothing I can do will make the nic function, even rebooting
and picking ipxe, or rebooting, hitting F11 and using the stock pxe in the
nic's rom.

I have to pull power/battery from the laptop to reset it.
