Chapter 2. Reporting RHEL for Real Time bugs

Identifying which kernel, the RHEL for Real Time or the standard kernel, is causing the problem might increase the chances of getting your bug fixed. This section covers information on how to diagnose a bug and report it.

2.1. Diagnosing RHEL for Real Time bugs

This procedure guides you how to diagnose where the problem has occurred before you file a bug report.

Prerequisite:

  • The latest version of RHEL for Real Time kernel is installed.

Procedure:

  1. Verify that you have the latest version of the RHEL for Real Time kernel.
  2. Boot into RHEL for Real Time kernel using the GRUB menu.
  3. If the problem occurs, report a bug against RHEL for Real Time.

  4. Try to reproduce the problem with the standard kernel.

    This troubleshooting step might assist in identifying the problem location.

Note

If the problem does not occur with the standard kernel, then the bug is probably the result of changes introduced in the RHEL for Real Time specific enhancements, which Red Hat has applied on top of the baseline (4.18.0) kernel.

2.2. Submitting a bug report with Bugzilla

If you have determined that the bug is specific to Red Hat Enterprise Linux for Real Time follow the instructions in this section to submit a bug report:

Prerequisite:

Procedure

  1. Log into your Bugzilla account.
  2. Click Enter A New Bug Report.
  3. Select Red Hat classification.
  4. Select the Red Hat Enterprise Linux product.
