Summary: 1: Need to add 14.10 images from Releases Stream to even see hwe-u as an option 2: even though hwe-u is an option, it is unusable for commissioning currently (from Releaess). 3: We really need this usable in Releases, it's gating the Power 8 work.
This morning I tried working on this a bit. Keep in mind, I did this on a non-Power system because I don't have easy access to it right now, and Mike is working on that. First, I had to install 14.10 installation media from the Releases stream. Once that was done, hwe-u became an option. Next, I clicked acquire node. Then Edit node. In the Edit screen, I set the ARCH to amd64/hwe-u, saved that and then clicked Commission to start the Commissioning process. The node powered up and failed to boot. The console says Booting under MAAS direction... nomodeset iscsi_target_name=iqn.2004-05.com.ubuntu:maas:ephemeral-ubuntu-amd64-hwe-u-trusty-no-such-image iscsi_target_ip=10.0.0.1 iscsi_target_port=3260 iscsi_initiator=these-grandmother ip=::::these-grandmother:BOOTIF ro root=/dev/disk/by-path/ip-10.0.0.1:3260-iscsi-iqn.2004-05.com.ubuntu:maas:ephemeral-ubuntu-amd64-hwe-u-trusty-no-such-image-lun-1 overlayroot=tmpfs cloud-config-url=http://10.0.0.1/MAAS/metadata/latest/by-id/node-d4c27b9-d7ee-11e4-8a03-eca86bfb9f66/?op=get_preseed log_host=10.0.0.1 log_port=514 Could not find kernel image: ubuntu/amd64/hwe-u/trusty/no-such-image/boot-kernel boot: So since setting the arch to amd64/hwe-u failed to boot commissioning, I changed it to amd64/hwe-t and retried. hwe-t was successful in booting the server and commissioning it. Following commissioning, I attemped to just install the node using hwe-u after it was commissioned using hwe-t. I clicked acquire node. Then Edit Node. On the Edit Page, I set the arch to amd64/hwe-u, and left the OS and Release to Default (which is currently set to 14.04). I then tried to start the node for deployment. The node powered on and attempted to TFTP boot, but instead got a TFTP timeout error. It then automatically moved to the next NIC and again got the TFTP timeout, and at this point it just booted what was on the hard disk. Could not find kernel image: ubuntu/amd64/hwe-u/trusty/no-such-image/boot-kernel" Next, for completeness, I re-acquired the node, left arch at hwe-u and set the OS to Ubuntu and Release to 14.10 to see what would happen. With those settings, I was able to successfully deploy the system with Utopic. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1425699 Title: kernel panic on IBM Power8 PPC MAAS ephemeral image Status in Maas image builders: New Status in linux package in Ubuntu: Confirmed Status in linux source package in Trusty: Confirmed Bug description: The kernel running on the 14.04 ephemeral image for MAAS when commissioning an IBM Power8 PPC server causes a periodic kernel panic.
