OMV 1.0 didn't boot after update from 0.5 and after fresh install of 1.0

That raid is through hardware controller? Or it was made from mdadm?

Is hard to tell, the best info of the traceback is at the beginning (what the screen already ate). I would then try a more up to date kernel OMV-extras provide the option to install kernel 3.16, but you can't even boot.
Can you still boot to 2.6? saw you did fresh install

And also do you have any peripherals connected (usb devices, pci cards, etc)? What about the BIOS revision? I see in the webpage a 2014 august revision.

I would try an 0.5 install, the upgrade to 1.0. Once there boot 2.6 kernel and update to 3.16 manually by cli.

Try AHCI.

Also you can redirect the boot sequence to text if you have a serial to USB cable, you need to edit the boot grub line in the menu at boot. Then you connect through putty and log everything into a txt file. But that would be just a log of kernel error, we cannot do much here about that.

Also it would be good to try an updated kernel on that. Other suggestion would be a minimal wheezy install, check if it boots, then install on top omv.
