<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">I’m Li Na from Lenovo xClarity team, working on OS deployment component. Our team had contacted with you before to enable IPv6, and now we’re planning to upgrade ipxe to the latest. But during UT, we’ve found
some issue:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">With latest ipxe source code, we built new image to boot elilo and then load initrd for linux, but it always hangs after loading is done. With the error code
<a href="http://ipxe.org/err/2a0860">2a0860 </a>on the screen, it points to “Error: No buffer space available”. And this out-of-space error seems also explaining why ramdisk fails to run. So is there any recent ipxe code change may lead to this issue? Or what
could we do to make this latest ipxe work for us?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
