I built a test kernel with a revert of 06f7e3d39 and a new backport of a048a07d7f4. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1773162

Can you test this kernel and see if it resolves this bug?

Note about installing test kernels:
• If the test kernel is prior to 4.15(Bionic) you need to install the linux-image and linux-image-extra .deb packages.
• If the test kernel is 4.15(Bionic) or newer, you need to install the linux-modules, linux-modules-extra and linux-image-unsigned .deb packages.

Thanks in advance!

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Hi Kalpana/ Pavithra,
I see your comments on the external bugzilla about the verification of bionic kernel for this issue.
Can you please confirm if this can be moved to resolved state from the testing perspective?

Thank you.

We have used below bionic "-proposed" path to get install it freshly, still it fails to boot.

Issue is still observed after installing from http://ports.ubuntu.com/ubuntu-ports/dists/bionic-proposed/main/installer-ppc64el/current/images/netboot/ubuntu-installer/ppc64el/

Please advice with the right path to pick the fixed kernel.

Did you passed the following boot parameter while installing 18.04 from proposed?
"apt-setup/proposed=true"

There has been no build of debian-installer in bionic-proposed against the 4.15.0-22 kernel reported to have this issue. The 4.15.0-24 kernel is now released to bionic-updates. So there should be no changes required on debian-installer for this.

Bionic is still completely uninstallable (via MAAS) because of this. MAAS is booting (currently) 4.15.0-23 for Bionic deployments and the oopese still occur sending the machine into a reboot loop.

^^ I also note that the fix is in -24, so I'll re-confirm once that is available via MAAS.

LP1773973 tracks the same issue.
Note from Kalpana -
With 'apt-setup/proposed=true', the boot is successful. This bug can be closed.
