An up-to-date listing of known issues can be found on the MRG Realtime Wiki: Known Bugs. Always check this list before reporting a new bug.
Before you a file a bug report, follow these steps to diagnose where the problem has been introduced. This will greatly assist in rectifying the problem.
Try reproducing the problem with the standard kernel. Check that you have the latest version of the Red Hat Enterprise Linux 5.1 kernel, then boot into it from the grub menu. Try reproducing the problem. If the problem still occurs with the standard kernel, report a bug against Red Hat Enterprise Linux 5.1 NOT MRG Realtime.
If the problem does not occur when using the standard kernel, then the bug is probably the result of changes introduced in either:
The upstream kernel on which MRG Realtime is based. For example, Red Hat Enterprise Linux 5.1 is based on kernel version 2.6.18 and MRG Realtime is based on version 2.6.21
MRG Realtime specific enhancements Red Hat has applied on top of the baseline (2.6.21) kernel
To determine the problem, it is helpful to see if you can reproduce the problem on an unmodified upstream 2.6.21 kernel. For this reason, in addition to providing the MRG Realtime kernel, we also provide a vanilla kernel variant. The vanilla kernel is the unmodified upstream kernel build without the MRG Realtime additions.
If you have determined that the bug is specific to MRG Realtime follow these instructions to enter a bug report:
You will need a Bugzilla account. You can create one at Create Bugzilla Account.
Once you have a Bugzilla account, log in and click on Enter A New Bug Report.
You will need to identify the product the bug occurs in. MRG Realtime appears under Red Hat Enterprise MRG in the Red Hat products list. It is important that you choose the correct product that the bug occurs in.
Continue to enter the bug information by designating the appropriate component and giving a detailed problem description. When entering the problem description be sure to include details of whether you were able to reproduce the problem on the standard Red Hat Enterprise Linux 5.1 or the supplied vanilla kernel.
