Also I have determined where it is getting hung at -- core/elflink/load_env32.c in start_ldlinux at rv = spawn_load(LDLINUX, argc, argv); Do you have any other ideas for troubleshooting?

It applies on top of, http://syslinux.zytor.com/archives/2011-April/016369.html The deletions in the diff stat below are mainly from deleting com32/elflink/modules (finally!).

From: Matt Fleming <matt.fleming at linux.intel.com> These patches are based on the elflink branch. This set of patches is my attempt at moving the command-line interface functionality out of the core and into an ELF module to reduce the size of the core. The most interesting patch is [PATCH 4/4] which moves the cli code out of core/elflink and into com32/elflink/modules. [PATCH 4/4] is
