interesting, so this is the same problem i was seeing on the Asus/amd
machines here...
the commit log for 1.47 mention interrupt issues which are consistent
with the random hangs or errors that I see while booting over the
network.

I wonder if the hangs are related to interrupts coming in at the
wrong time. I also wonder whether the same symptoms might also
affect the standard loader and not just pxeloader, in which case
the problem would be slightly more serious.
I am afraid my ability to debug the problem isn't going much
beyond this...
