<p class="MsoNormal"><span style="font-size:11.0pt">Unfortunately, we have run into a similar issue before. Our build system is completely automated and there is no way to inject the `make menuconfig` interactive step into that process. If I were to be testing
this locally I might be able to work something out, but I could never get such a build into our testing environment which is where the crashes are occurring.</span><o:p></o:p></p>

up” and sent a burst of 200 OK responses. The crash seems to have occurred processing the ACK to one of these responses.</span><o:p></o:p></p>
