3.7.1 update worked but over heated

id the 3.7.1 update from ADS-B Network News. Simple enough. up and running at 19:31 hrs on 5/22. RaspPi overheat around 10:00 hrs 5/23. Last code:
[ 150075201] —[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)

What hardware needs to be replaced?

Most likely none. There seems to be some problem when updating from old installs.

Just write piaware to the sd-card as described by step 2 of the following page:
PiAware - build your own ADS-B ground station for integration with FlightAware - FlightAware

You might want to save your piaware-config.txt somewhere else before and also add your feeder-id.
For Beginners - How to Get Back Existing Station Number in A Fresh Install

Then when you have written the image use the piaware-config.txt you saved and put the sd-card back in the RPi.
Should all work fine.
