3. Known Problems in this Release

Open source projects are continuously working on correcting reported problems. Fixes and workarounds to bugs detected by Enea are submitted upstream, and included in Enea Linux regardless of when they will be included by the open source project. Issues that still affect the current release are listed below. 3.1 Yocto Project

The Yocto Project community uses a Bugzilla database1 to track information on reported bugs and other issues. 3.2 Devtool

The following command does not work for raspberrypi. This is a limitation originating from raspberrypi qemu support.

$ devtool runqemu enea-image-standard nographic slirp 3.3 KGDB kernel debugging

The KGDB kernel debugging scenario described in section 7.5 Debugging the Linux Kernel in Eclipse in the Enea Linux User's Guide, was not validated for this release.

4. Contacting Enea Support

Technical support for all Enea licensed and supported products can be requested via EneaIssues (https:// eneaissues.enea.com), via e-mail mailto:[email protected] or telephone. Addresses and phone numbers for local support can be found at: http://www.enea.com/support. 4.1 Request for Product Support

Before reporting a problem or defect to the Enea Global Support, please perform the following checks:

• Check the user documentation for the Enea product(s), including trouble shooting sections. • Check if the issue you request support for is supported by Enea (see the release documentation about which components are included in your delivery). • Check any information found via http://www.enea.com/support. • Check whether the problem is specifically related to your application or if it is an error generated by an Enea product.

In order to effectively resolve reported problems, we kindly ask Enea's customers to provide Enea Global Support with sufficient information to identify and isolate the specific problem or defect. We recommend using EneaIssues (https://eneaissues.enea.com), also available at http://www.enea.com/support. Report a bug, ask for a new feature, or just ask a question.

See Section 4.2, Support Issue Information [27], listing information to provide in a support issue to ensure the issue can be processed as fast as possible. Below are some further explanations.

If possible, please try to provide relevant and basic information such as the following:

• Name of the software product component. • Version Number. • Error Messages. • Documented sequence of events to reproduce the problem.

Please also communicate the severity level of this problem or defect to Enea Global Support for priority purposes. Currently, the following levels of severity are defined:

• Minor - The Product(s) functionality operates abnormally. If the Error occurs during the development phase of a Customer's product, the development, integration, or testing is inconvenienced. Alternately, the Customer requires information or assistance with respect to the Product(s) capabilities, installation, or configuration. • Serious - The Product(s) functionality operates with severely reduced capacity causing significant impact to business operations. If the Error occurs during the development phase of a Customer's product, the Error has serious impacts on the development, integration, or testing. A workaround may be available. • Critical (showstopper) - The Product(s) functionality is inoperable causing critical impact to business operations, if the functionality is not restored quickly. If the Error occurs during the development phase of a Customer's product, the Error hinders all of the Customer's development, integration, or testing. No viable workaround is known.

Each reported issue is assigned a problem identification number and is managed using a defect tracking system: EneaIssues. Once a problem has been received, Enea Global Support will send a receipt for the issue. Guidelines for (external) users of EneaIssues are available in the EneaIssues User's Guide1.

4.2 Support Issue Information

The following information is to be provided by a customer in a support issue (https://eneaissues.enea.com), to enable Enea support to process the issue in fastest possible way. The customer could copy this text, add information and paste it into the issue report description (* denotes mandatory information).

1. * Problem title (Well describing the problem, please avoid using customer specific words).

2. Basic information (should be accurate and detailed - mandatory if issue is critical). • How is the problem affecting your business? • Problem impact? On which level in the system does it occur [in operation/upstart/upgrade]? • Is the problem preventing you from shipping your product? • Is the problem located in development, at applications or at an end customer?

3. * Question, probable Bug or New Feature [not part of current product definition] (Q, B or FR).

4. * Estimated Problem severity: Critical (A), Serious (B) or Minor(C). • Critical (showstopper) - The system is unusable until a fix is available. • Serious - A component of the system is unusable until a fix is available. • Minor - Little or no impact on the use of the product.

5. * Enea Product and Version, detailed enough to identify exactly which version is used. • Product release and if applicable, component version. See below. • Possibly customer specific component? • Development Host platform and Host OS version (if applicable)? • Target architecture e.g. PPC440EP Bamboo (if applicable)? • Compiler/toolset, compiler flags and version?

6. * Problem description (Should be accurate, detailed and explain the problem in terms of Enea product concepts and components. Customer specific abbreviations or words should be avoided or explained).

7. * Describe if the problem can be reproduced/verified: • Is the problem reproducible (frequency => x out of y times)? • Is the problem reproducible with the latest product release? See below. • Do you have a workaround? - if yes, please clarify.

8. Information to help identify the cause of the problem: • A reasonable investigation of the issue that makes you believe the problem is with the Enea product. • Please provide a step by step guide with necessary reference/sample code so we are able to recreate the problem at our site? • What pre-conditions are necessary to recreate the fault? • Does the error origin from the host or target? Append applicable files - see below. • What drivers are involved? Have any drivers been modified? • Wireshark traces or information from probes like RiskWatch. Append applicable files - see below

9. Product specific information and appended files: • Product release (e.g. Enea-Linux-), component version (e.g. busybox X.Y.Z). • Reproducable (or not) with latest release (e.g. Enea-Linux-). • dmesg files (Y/N)? File names: • Kernel Oops file (Y/N)? File names: • core. file? (Y/N)? File names: • Configuration files (Y/N)? e.g. in /etc. File names: • Trace log files (Y/N)? e.g. in /var/log. File names:

4.3 Software Updates

Major product releases are currently scheduled regularly. Major releases include cumulative upgrades containing corrections to Enea licensed products and new functionality included in the licensed products. Maintenance updates and patches are provided for corrections to known problems and are available upon request.

Some special products, existing in many variants for different ranges of targets and supported major products, can be updated and provided depending on demands, instead of regularly. Please contact Enea Global Support for further information. 4.4 Extended Support Services

Extended maintenance options are available for an additional fee that is determined based on the selected services. Potential Extended Support Services could include on-site support, support reviews, and a higher grade of support.
