for all of you that want to have their a 4.x kernel running OMV 2 you can download them here.
Current 4.6 (Do not Upgrade to 4.6, if you need VirtualBOX - Currently there is an issue with the DKMS. If you want still to run it, manually apply this patch for the kernel driver)
Installation with: dpkg -i linux-*.deb
You should install headers & image. On top I suggest before moving from kernel 3.X to 4.X to install the btrfs tools.
You can load them here, and install via dpkg -i <PAKAGENAME>
This images include the e1000 modules and the USB modules to boot from a USB Stick or disk.
For all baytrail users, they are stuggeling with system crashes on kernels > 3.10 (compare this link) please limit the max c_states = 1 in the Bios or via Grub, to get a stable NAS again.
