+Background
+==========
- What follows is a suggested procedure for reporting Linux bugs. You
-aren't obliged to use the bug reporting format, it is provided as a guide
-to the kind of information that can be useful to developers - no more.
+The upstream Linux kernel maintainers only fix bugs for specific kernel
+versions. Those versions include the current "release candidate" (or -rc)
+kernel, any "stable" kernel versions, and any "long term" kernels.
+
+Please see https://www.kernel.org/ for a list of supported kernels. Any
+kernel marked with [EOL] is "end of life" and will not have any fixes
+backported to it.
+
+If you've found a bug on a kernel version isn't listed on kernel.org,
+contact your Linux distribution or embedded vendor for support.
+Alternatively, you can attempt to run one of the supported stable or -rc
+kernels, and see if you can reproduce the bug on that. It's preferable
+to reproduce the bug on the latest -rc kernel.
+
+
+How to report Linux kernel bugs
+===============================
+
+
+Identify the problematic subsystem
+----------------------------------
+
+Identifying which part of the Linux kernel might be causing your issue
+increases your chances of getting your bug fixed. Simply posting to the
+generic linux-kernel mailing list (LKML) may cause your bug report to be
+lost in the noise of a mailing list that gets 1000+ emails a day.
+
+Instead, try to figure out which kernel subsystem is causing the issue,
+and email that subsystem's maintainer and mailing list. If the subsystem
+maintainer doesn't answer, then expand your scope to mailing lists like
+LKML.
- If the failure includes an "OOPS:" type message in your log or on
-screen please read "Documentation/oops-tracing.txt" before posting your
-bug report. This explains what you should do with the "Oops" information
-to make it useful to the recipient.
- Send the output to the maintainer of the kernel area that seems to
-be involved with the problem, and cc the relevant mailing list. Don't
-worry too much about getting the wrong person. If you are unsure send it
-to the person responsible for the code relevant to what you were doing.
-If it occurs repeatably try and describe how to recreate it. That is
-worth even more than the oops itself. The list of maintainers and
-mailing lists is in the MAINTAINERS file in this directory. If you
-know the file name that causes the problem you can use the following
-command in this directory to find some of the maintainers of that file:
+Identify who to notify
+----------------------
+
+Once you know the subsystem that is causing the issue, you should send a
+bug report. Some maintainers prefer bugs to be reported via bugzilla
+(https://bugzilla.kernel.org), while others prefer that bugs be reported
+via the subsystem mailing list.
+
+To find out where to send an emailed bug report, find your subsystem or
+device driver in the MAINTAINERS file. Search in the file for relevant
+entries, and send your bug report to the person(s) listed in the "M:"
+lines, making sure to Cc the mailing list(s) in the "L:" lines. When the
+maintainer replies to you, make sure to 'Reply-all' in order to keep the
+public mailing list(s) in the email thread.
+
+If you know which driver is causing issues, you can pass one of the driver
+files to the get_maintainer.pl script:
perl scripts/get_maintainer.pl -f <filename>
- If it is a security bug, please copy the Security Contact listed
-in the MAINTAINERS file. They can help coordinate bugfix and disclosure.
-See Documentation/SecurityBugs for more information.

- If you are totally stumped as to whom to send the report, send it to
-linux-kernel@vger.kernel.org. (For more information on the linux-kernel
-mailing list see http://www.tux.org/lkml/).
+If you can't figure out which subsystem caused the issue, you should file
+a bug in kernel.org bugzilla and send email to
+linux-kernel@vger.kernel.org, referencing the bugzilla URL. (For more
+information on the linux-kernel mailing list see

+
+Gather information
+------------------
+
+The most important information in a bug report is how to reproduce the
+bug. This includes system information, and (most importantly)
+step-by-step instructions for how a user can trigger the bug.
+
+If the failure includes an "OOPS:", take a picture of the screen, capture
+a netconsole trace, or type the message from your screen into the bug
+report. Please read "Documentation/oops-tracing.txt" before posting your
+bug report. This explains what you should do with the "Oops" information
+to make it useful to the recipient.
