Thank you for your help. In fact, there are two problems: 1. core/console.c contains the standard PC UART (COM1) initialization code executed unconditionally during startup before PCI network device enumeration is performed. Our board has no standard PC UARTs, and this is the reason why this takes 15-20 seconds to start enumerating devices. This was relatively easy to fix. No startup delays anymore. 2. further device enumeration is not stable, only 4-5 attempts from 10 are successful. In all other cases it just clears the screen and hangs forever. My sleuthing has shown that this happens somewhere in pci device probing code. Will go deeper. I'm building from code downloaded on 16-sep-2014 [master branch]. gcc v4.7.2, came with Debian 7/32 bit. Interesting fact that the pre-built Ubuntu 12.04 binary package (ipxe_1.0.0+git-3.55f6c88-0ubuntu1) also has the #1 described above, but doesn't have #2 Any thoughts and suggestions will be greatly appreciated.
