Clean install openmediavault_3.0.36-i386 with following updates -> kernel panic with 3.16.0-6-686-pae and above

I am trying to prepare a new system on a virtual machine (virtual box, 32-bit, 1 GB RAM) based on the 3.0.36. I assume, this is the most recent 32-bit Openmediavault-ISO available.

The initial setup runs smooth, however, updating this through the web-gui with all available updates, the underlying 3.16.0-4-686-pae is updated as well to 3.16.0-6.686-pae, which causes a kernel panic during reboot. The exit code is 0x0000000b, however I am not sure, if this helps a lot. By switching back to the initial kernel in the advanced options of grub, I can start the system as expected.

Any ideas? For the 2.x this approach of setting up a test bench used to work.

Of course, however I assumed the other way would be the more direct and easy approach.

In general I am confused, that an update within the Openmediavault-environment is actually breaking a running system and would have thought, that all packages updated within this environment are somehow harmonized.
