Updating from 15.4 directly to 15.6 did not work for you. You can try that again and hop that it works this time, or you can update first to 15.5, then to 15.6, which will work. Your choice.
No, it will not work, there is boot crash of the image, a kernel crash.
A zypper dup might work, or the kernel could also crash on the following first boot.
Zypper online upgrades done with kernel locked will leave the old kernel installed, and not install a new one. I keep kernel locked as a matter of course, and choose the time for new kernel installation independently from other processes. Upgrade can be performed this way, then booted on old kernel, only after which installing new without removing old. It's a little like having a snapshot to fall back on. Working old remains available for use in case new fails.
Hum. Risky, methinks.
If old initrd is not backed up or locked, upgrade could make booting new system fail without recourse, by having regenerated initrd for each old kernel. Once I have a working initrd for a kernel, I make it immutable to prevent such any such possibility, and leave that way until time to remove its kernel.
