You can install multiple kernel versions at the same time on openSUSE system.

But, first off, verify whether you're using Secure Boot or not.  If yes, you'd
need to disable Secure Boot on BIOS at first.  The way depends on the machine.

Then, as a preparation, increase the number of multiple installable kernels by
editing /etc/zypp/zypp.conf as root.  Add more entries to the line
multiversion.kernels, e.g.
  multiversion.kernels = latest,latest-1,latest-2,latest-3,running

Now, go to the download URL.  Choose x86_64 instead of i686.  e.g. for 6.0,
from
 
http://download.opensuse.org/repositories/home:/tiwai:/kernel:/6.0/standard/x86_64/
and download kernel-default-6.0.*.rpm file from there.

Install it via zypper,
  % zypper in --oldpackage kernel-default-6.0.*.rpm

You'll be asked for the signature, but you can ignore it and continue.
After installing, reboot, choose the kernel on GRUB menu, and retest.

If the kernel isn't needed any longer, uninstall it
  % zypper rm kernel-default-6.0.12

The i686 is a wrong one, that's for 32bit.

We'd need to report this to the upstream in the end, but at first we need to
figure out whether a regression and the exact regression range if so.
