Karnel modules fail to load-why?

Asked by Navin Talati on 2017-05-12

When I starts my system, while booting (i.e. before Login screen) it appears warning on the black-screen stating "Failed to start load Kernel Modules". Then onward the usual Login screen appears and could be login as usual.
Why this happens?
How to find which kernels' modules are installed in the system?
How to find which kernels' modules fail to load?
How to remove unnecessary kernels?
Please state the required command lines and help me to resolve the issue.
Thanks in anticipation.

Does the server startup OK despite the message?

Navin Talati (n-m-talati) said : #2

After login to the system everything goes normal and also Firefox browser works normally. Thus I understand that the server start-up is OK. If some command is there to assess the server start-up and its activities, please give me the relevant stuff so that I can upload the out-put to check further.

Is there any additional information shown besides "Failed to start load Kernel Modules", e.g. the name of the module that could not be loaded?

You could also use the system log viewer to search for messages that provide a more detailed description of what failed.
And the file /var/log/kern.log and the dmesg command might also be able to reveal the cause of the error message.

Can you help with this problem?
