Hi Chris,

We investigated the failure job and looks like before getting login prompt job
timeout is happening . In the job definition file - job timeout is mentioned
15mins and sometimes due to slow network issue, it takes more time while
downloading, untar and deploying image. So we are seeing timeout during
login prompt or in some cases in earlier stages also. The work in progress to
double up the network bandwidth within a few weeks, which will reduce the
occurrence of this type of issues.
Thank you for your investigation.
I've have increased the timeout as you have suggested:

One additional thing I've noticed, the default x86 character delay during boot is 500ms, which seems a long time inbetween each character sent to the platform

Has a lower value for boot_character_delay ever been tried?

Kind regards, Chris

Time being, with an increased job timeout to 20mins, failure is not observed.
We tested 10 times to be working fine.
Example :

changes in the job definition file
Current implementation
minutes: 15

Need to Modify
minutes: 20

It is not first time I see this failure:
Thank you for reporting the issue.

Bikram is going to take a look for us (thank you).

Kind regards, Chris;data=04%7C01%7CChris.

Any idea what is going on there? Is it just a test problem, or do we
have kernel regression that only happens sometimes?
