Public bug reported:
Description: During SRU Testing of various Azure Instances, there will
be some cases where the instance will not respond following a system
reboot. SRU Testing only restarts a giving instance once, after it
preps all of the necessary files to-be-tested.
Series: Disco
Instance Size: Basic_A3
Region: (Default) US-WEST-2
Kernel Version: 4.18.0-1013-azure #13-Ubuntu SMP Thu Feb 28 22:54:16 UTC 2019
x86_64 x86_64 x86_64 GNU/Linux
I initiated a series of tests which rebooted Azure Cloud instances 50
times. During the 49th Reboot, an Instance failed to return from a
reboot.. Upon grabbing the console output the following was seen
scrolling endlessly. I have seen this failure in cases where the
instance only restarted a handful of times >5
