Comment 32 for bug 1873809

@Stefan, so actually this is an actual regression.

1015 will boot just fine in LXD with secureboot disabled.
1017 will not boot at all in LXD with or without secureboot disabled.

I don't know if it's switching to a signed kernel which causes the lz4 issue but the result is a clear regression so I would not consider this kernel suitable for release to anyone.
