Bug Description


could you please update the installer to use linux-hwe version >= 4.10.0-29 for POWER9 on Xenial.

At the moment the kernel/vmlinux in http://ports.ubuntu.com/ubuntu-ports/dists/xenial-proposed/main/installer-ppc64el/current/images/hwe-netboot/ubuntu-installer/ppc64el/ is based on
linux 4.10.0-28 which doesn't include this ERAT related patch (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1700521 and other P9 fixes also) which cause the installer to fail on POWER9.

A move to hwe kernels with version greater than 4.10.0-29 should work.
Thanks a lot.

Hello Frédéric, or anyone else affected,

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, details of your testing will help us make a better decision.

Frédéric, can you please verify that the current xenial-proposed image does boot on POWER9? We are currently awaiting this confirmation before publishing the updated debian-installer package to xenial-updates.

Hi Steve,
sorry for the delay, I've been afk. I'll check this today and let you know.

Hi again,
I tested the latest netboot installer there http://ports.ubuntu.com/ubuntu-ports/dists/xenial-proposed/main/installer-ppc64el/current/images/hwe-netboot/ubuntu-installer/ppc64el/ and it worked perfectly.
