<p class="MsoPlainText"><span lang="EN-US">I recently noticed that iPXE as of the latest commit to this day (built on my rhel 6/7 client and Ubuntu 15), cannot boot a 32bit rhel 5 pxeboot kernel/initrd image (I have tested 5u3, 5u8, 5u11 images).<o:p></o:p></span></p>
<p class="MsoPlainText"><span lang="EN-US">iPXE will just "crash/reboot". Funnily enough my 32bit rhel 6 images works fine.<o:p></o:p></span></p>

<p class="MsoPlainText"><span lang="EN-US">Going back in time to the last good known state (I had downloaded in June 2014), then going back and forth (some months/commits) A LOT, I managed to locate where it would stop working, so I could reproduce this behavior.<o:p></o:p></span></p>
