This is caused by a seg fault while trying to parse the fdt argument, as
pxe is always calling do_bootm with argc == 4.
The patch with the fix http://people.canonical.com/~rsalveti/pxe/0001
-cmd_pxecfg-only-call-do_bootm-with-argc-4-if-fdtaddr.patch.
And the binary with the fix included:
http://people.canonical.com/~rsalveti/pxe/3/u-boot.bin
With the fix PXE works as expected:
