CAUTION: 32bit CPU attempting to boot an untagged Linux image.
If system hangs, power cycle and set boot file to a 32bit image.

Acme Packet Net-Net 3820
Processor speed: 1.866 GHz
Stage 1 (built Nov  1 2013 11:09:15)
/boot: volume uses UTF-16 on disk, but Unicode is disabled
Stage 2 (built Nov  1 2013 11:09:15)

Resolution is to boot back to previous image by changing the /boot/oldimage and freeing up space on the /boot/ folder. revert back to new image and it should upgrade.

other possibilities could be incorrect stage3 bootloader.
