Issue with Realtek card and iPXE

[m_theredhead]

I have a few boxes that I net boot using gpxe including one box with a realtek card. Under Linux, it shows up as:

04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)

Using gpxe 1.0.1, it would fail to boot with the message “initialising devices…". This is also reflected in the etherboot wiki: http://etherboot.org/wiki/hardwareissues. However, I used the rom-o-matic to build a 1.0.1+ version of undionly and it has worked well on this motherboard for at least a year. I assumed the issue was resolved.

So today, when I upgraded to iPXE, I was a little surprised to see this error message return. Does anyone have any suggestions why it would work in gpxe 1.0.1+, but not with a current version of ipxe?

What is the best way to debug this?
