Comment 19 for bug 1864897

Kernel installed as described in https://wiki.ubuntu.com/Kernel/MainlineBuilds . First dpkg -i linux-image-unsigned-5.6.0-050600rc4-generic_5.6.0-050600rc4.202003012332_amd64.deb was terminated unsuccessfully with error messages; trying it again as last instead of third file yielded several messages but worked. The test kernel boots OK, i. e., the password for disk decryption is asked for and afterwards the user password.
