I have installed the P8 Hardware with Ubuntu 14.04.3 and executed the test scenario again.

ibmpowernv 4808 0

No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): YES
modprobe: FATAL: Module cpuid not found.
Failed to load module cpuid.
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 10h thermal sensors... No
AMD Family 11h thermal sensors... No
AMD Family 12h and 14h thermal sensors... No

Intel digital thermal sensor... No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): YES
Sorry, no supported PCI bus adapters found.

Next adapter: p8_00000008_e0p0 (i2c-0)
Do you want to scan it? (YES/no/selectively): YES
Client found at address 0x50
Handled by driver `at24' (already loaded), chip type `24c128'
(note: this is probably NOT a sensor chip!)
Client found at address 0x51

Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.

root@ltc-fire8:~# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
root@ltc-fire8:~# echo $?
1

root@ltc-fire8:~# cat /boot/config-3.19.0-25-generic | grep -i ibmpowernv
CONFIG_SENSORS_IBMPOWERNV=m
root@ltc-fire8:~# cat /boot/config-3.19.0-25-generic | grep -i powernv
CONFIG_PPC_POWERNV=y
CONFIG_PPC_POWERNV_RTAS=y

CONFIG_IPMI_POWERNV=m
CONFIG_HW_RANDOM_POWERNV=m
CONFIG_SENSORS_IBMPOWERNV=m
CONFIG_CRYPTO_DEV_NX_COMPRESS_POWERNV=m

So, still the issue exists even with the latest build of Ubuntu 14.04.3
