-[Some of this is taken from Frohwalt Egerer's original linux-kernel FAQ]
+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.
 
-     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.
+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.
 
-      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:
+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.
+
+
+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 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 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
+http://www.tux.org/lkml/).

+
+
+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

+=========
+
+Expectations for bug reporters
+------------------------------
+
+Linux kernel maintainers expect bug reporters to be able to follow up on
+bug reports.  That may include running new tests, applying patches,
+recompiling your kernel, and/or re-triggering your bug.  The most
+frustrating thing for maintainers is for someone to report a bug, and then
+never follow up on a request to try out a fix.
+
+That said, it's still useful for a kernel maintainer to know a bug exists
+on a supported kernel, even if you can't follow up with retests.  Follow
+up reports, such as replying to the email thread with "I tried the latest
+kernel and I can't reproduce my bug anymore" are also helpful, because
+maintainers have to assume silence means things are still broken.
+
+Expectations for kernel maintainers
+-----------------------------------
+
+Linux kernel maintainers are busy, overworked human beings.  Some times
+they may not be able to address your bug in a day, a week, or two weeks.
+If they don't answer your email, they may be on vacation, or at a Linux
+conference.  Check the conference schedule at LWN.net for more info:
+	https://lwn.net/Calendar/
+
+In general, kernel maintainers take 1 to 5 business days to respond to
+bugs.  The majority of kernel maintainers are employed to work on the
+kernel, and they may not work on the weekends.  Maintainers are scattered
+around the world, and they may not work in your time zone.  Unless you
+have a high priority bug, please wait at least a week after the first bug
+report before sending the maintainer a reminder email.
+
+The exceptions to this rule are regressions, kernel crashes, security holes,
+or userspace breakage caused by new kernel behavior.  Those bugs should be
+addressed by the maintainers ASAP.  If you suspect a maintainer is not
+responding to these types of bugs in a timely manner (especially during a
+merge window), escalate the bug to LKML and Linus Torvalds.
+
+Thank you!
