Comment # 1 on bug 1201439 from andreas bittner

i think the last two updates it just applied (zypper ref and zypper up) right
before i rebooted the machine were the mdadm and the x11-org updates as also
given on that mailing list overview.

the kernel update seems only been released for 15.3 so far. so I dont know why
it fails to reboot.

I think I just rebooted this machine the other day some day ago or so when
there was some rather larger plasma desktop patches or so.

booted fine during the past few weeks ever since I installed it.

FDE, I always had to prompts for the password, one at the very beginning right
out of the UEFI stage, and then one after selecting the first entry in the
grub2 menu to boot the normal 15.4 kernel.

it asked my twice for a boot. then happily booted into the kde plasmal login
screen.
