[Bug 1962012] [NEW] BERT: Error records from previous boot: Firmware Error Record Type: SOC Firmware Error Record Type2, Revision: 2, Record Identifier: 8f87f311-c998-4d9e-a0c4-6065518c4f6d while training neural network on CPU

[Ryan Scott]

Public bug reported:

I was training a neural network on CPU using Tensorflow + Keras in
Python. The crash happened twice in the same day after installing an
update to Ubuntu.
