Comment # 3 on bug 1175908 from Harald Koenig

thanks! I've downloaded/installed/booted 

kernel-default-5.3.12-1.1.g60a2268.x86_64.rpm
kernel-default-5.4.14-1.1.gfc4ea7a.x86_64.rpm
kernel-default-5.5.13-1.1.g0af205d.x86_64.rpm
kernel-default-5.6.15-1.1.gbfa465b.x86_64.rpm
kernel-default-5.7.12-1.1.g9c98feb.x86_64.rpm

and only 5.3.12-1.1.g60a2268 successfully booted -- all other kernels are stuck
in the same "Failed to start Cryptography Setup for cr_sda5" error.

how to proceed ?

what are the magic spells for systemd to get more info at boot time when
failing?


AND what's really strange (for me): 

after testing/booting all your kernel pkgs and then booting into my working
5.3.12-2-default again, ALL  *your* kernel packages are gone again!!

before the (re)boot tests, "rpm -q/-qf" showed all your kernel packages,
all your versions showed up in grub2 'Advanced options for openSUSE Tumbleweed'
menu, and in grub I've seen the msg "loading kernel-5.4..." etc. (and the git
hashes in version)


$ rpm -qf /boot/vmlinu* | sort -u
kernel-default-5.3.12-2.2.x86_64
kernel-default-5.8.2-1.2.x86_64

$ rpm -q kernel-default
kernel-default-5.3.12-2.2.x86_64
kernel-default-5.8.2-1.2.x86_64

in /etc/zypp/zypp.conf I'm using:

  multiversion = provides:multiversion(kernel)
  multiversion.kernels = latest,latest-10,running


is there any "magic" removing any non-booting (or non-official-suse) kernel
RPMs at boot time ????

I'm using all ext4fs, so no btrfs issues are possible. 

and zypper history shows that I'm not dreaming:

$ egrep '(install|remove ).kernel-default' /var/log/zypp/history

so, what's going on here?
new ticket needed?
