To gather the information, a serial console connection is required. This can be done by using any application that supports console access and the capturing/saving of the output.
Windows HyperTerminal is being used in this example:
- Capture the data to a file. Transfer -> Capture Text and select the location of the capture text file. All console outputs will now be logged to this file.
- Run the following commands to enable the kernel debug (the break sequence varies from client-to-client):
Ctrl+Break (hold down the Ctrl key, press the Break key, and then release both keys) and then press 9; you should see the following output:
Leave the console connected. This is very important. When/If the issue occurs again…….
- Wait for a few minutes and then run the following commands to capture the kernel tracing:
Ctrl+Break (hold down the Ctrl key, press the Break key, and then release both keys), and then press t. The output should display a kernel trace.
- When it is completed, collect the file that was created in Step 1 for support analysis.
