Hi,<br>
<br>
I am using TripleO to deploy Stable Mitaka on HP BL460c Gen9 blades.<br>
<br>
I set my config up for grub2 (not Elilo) UEFI iPXE mode as per -<br>
<br>
<a href="http://docs.openstack.org/project-install-guide/baremetal/draft/setup-drivers.html" rel="noreferrer" target="_blank">http://docs.openstack.org/proj<wbr>ect-install-guide/baremetal/<wbr>draft/setup-drivers.html</a><br>
<br>
In UEFI mode I get a kernel panic on iPXE boot during introspection when I use<br>
the pre-built Mitaka CentOS images (<br>
<a href="http://buildlogs.centos.org/centos/7/cloud/x86_64/tripleo_images/mitaka/delorean/" rel="noreferrer" target="_blank">http://buildlogs.centos.org/ce<wbr>ntos/7/cloud/x86_64/tripleo_im<wbr>ages/mitaka/delorean/</a>)<br>
If I try building my own images with the latest CentOS cloud image I have the<br>
same problem.<br>
<br>
If I replace the kernel with the latest kernel from ELRepo then all works fine<br>
and I can introspect and create a working stack.<br>
<br>
This thread sort of explains the issue -<br>
<br>
<a href="http://forum.ipxe.org/showthread.php?tid=7813" rel="noreferrer" target="_blank">http://forum.ipxe.org/showthre<wbr>ad.php?tid=7813</a><br>
<br>
So It looks like this issue is fixed in a kernel that does not yet ship with<br>
CentOS.<br>
<br>
Has anyone else been struggling with this?<br>
<br>
I am probably going to revert to HP legacy BIOS mode as I don't want to run my<br>
stack on a non standard setup.<br>
<br>
Thanks<br>
<br>

Hi!<br>
<br>
Have you tried raising it to the kernel folks? I see that we need to backport <a href="http://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?id=819ab9941c98f18b0f8c7ffb815e4f07186d2a5f" rel="noreferrer" target="_blank">http://git.kernel.org/cgit/lin<wbr>ux/kernel/git/stable/linux-sta<wbr>ble.git/commit/?id=819ab9941c9<wbr>8f18b0f8c7ffb815e4f07186d2a5f</a><br>
