For this test the server never booted, looks both issues are related to virtioblk_transfer: Access beyond end of device!

@bgilbert Do you know if it could something disk related?

The ext.config.shared.kdump.crash one is odd. The regular kernel boots fine, and then the crashdump kernel crashes in a TPM driver before we ever reach userspace.

coreos.boot-mirror.luks removes a disk and then verifies that we can boot from the other one, but we apparently can't. I assume this test has previously worked on ppc64le? It could be a firmware issue, or it could be that we're no longer setting up the bootloader or mirroring correctly.

[ravanelli]

@bgilbert Thanks for the comments. I tried some downgrades, but they don't seem to work. We will need to debug it more to see if it should or shouldn't run on ppc64le. So far, these tests seem they never really worked.

[dustymabe]

With upstream commit bd7dc90 the ext.config.kdump.crash test passes again.

This is tagged in v6.1-rc1+. I tested with latest rawhide with kernel-6.1.0-0.rc2.21.fc38.ppc64le.
