Known good version: linux-image-4.15.0-10
I think it is the same bug like in
https://bugzilla.redhat.com/show_bug.cgi?id=1558977
The bug was introduced in the mainline kernel 4.15.4 with commit
"[46e8d06e423c4f35eac7a8b677b713b3ec9b0684] crypto: hash - prevent using keyed
hashes without setting key"
This bug should be fixed before releasing ubuntu18.04 by either
reverting the commit or using a fixed mainline kernel.
