Hangs on "initialising devices"

[IgniFerroque]

I've got a working iPXE setup where undionly.kpxe is fetched from tftp. I recently got a new computer where iPXE stalls at "iPXE initialising devices"

lspci on this computer gives this for the ethernet device:

Code:

01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 03)

It was suggested on the IRC channel to build iPXE with debug messages, so I found that the "iPXE initialising devices" was in core/main.c so I built iPXE like this:

Code:

make bin/undionly.kpxe EMBED=../contrib/default.ipxe DEBUG=main

I didn't see any debug message though. Using "DEBUG=undionly,undinet,pxeparent" led to this message:

Code:

iPXE initialising devices...UNDINIC 0x18140 using UNDI 0xc2234478

Does anyone have any suggestions on a direction to proceed?
