There has been an issue discovered, regarding some Ubuntu 32 bit kernels (3.19.0-*) on Hyper-V, that causes the Ubuntu guest machine to kernel panic on start-up.
The issue is not caused by RapidRecovery but with certain Ubuntu kernels inside Hyper-V. As per Ubuntu it appears to be a vmbus driver bug in Ubuntu 32bit kernels that causes the kernel panic and has been addressed and fixed in kernels 3.19.0-37.
It is unsure which exact kernels the issue has officially affected, as issues started being seen with kernel 3.19.0-25. However the issue could pre-date the 3.19.0-25 kernel.

To resolve this issue, upgrade your Ubuntu kernel to 3.19.0-37 or newer which contains the fix. Then take a new incremental snapshot and perform an export or BMR of the machine.
It should be noted that updating your kernel could break application compatibility so please check to be sure your applications are compatible with the updated kernel.
To update your kernel, for example, run:
apt-get install linux-image-3.19.0-37-generic
After upgrading, reboot your machine and you should now be running with the new kernel, unless you have a specific boot entry in which case see the following article to change the default kernel to the new one https://help.ubuntu.com/community/Grub2/Submenus
To check kernel version, run:
uname -r
