Comment: 1) Due to LP#1773643 RM archive URL as folks may "dive in" w/o knowing what to do. 2) Misc. softenings. 3) Misc. small phrasing chgs.

| ==== Old With No Activity ==== {{{ This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ . |
For some issues on some computers, the BIOS being outdated can cause various issues that seem due to Ubuntu itself. For example, hardware intermittently working, hardward not working at all, or what seems software dependent. Also, many upstream developers request this being updated, despite one having tested the latest mainline kernel, to help them rule out root causes. So, while it's not a requirement to have the BIOS updated before upstreaming, one is doing themselves, and upstream a great favor by ensuring it is. As a courtesy to the original reporter, one may provide the direct URL to the latest BIOS update, and note the version number. |

Introduction
This page offers kernel bug triagers suggested responses that have been found effective in obtaining requested information.
Request full computer model
For some computers, while computer details may be provided via the Bug Description, the full computer manufacturer and model aren't provided, or the details aren't accurate. Hence, if one is interested in reviewing the computer specifications from the vendor's website, one may request this via:
Could you please provide from the the sticker of the computer itself (not from the Bug Description, or the result of a terminal command) the full computer model? |
Request BIOS update
For some issues on some computers, the BIOS being outdated can cause various issues that seem due to Ubuntu itself. For example, hardware intermittently working, hardward not working at all, or what seems software dependent. Also, many upstream developers request this being updated, despite one having tested the latest mainline kernel, to help them rule out root causes. So, while it's not a requirement to have the BIOS updated before upstreaming, one is doing themselves, and upstream a great favor by ensuring it is. As a courtesy to the original reporter, one may provide the direct URL to the latest BIOS update, and note the version number.
As per your computer vendor's website, an update for the computer's buggy, insecure, and outdated BIOS is available. Could you please advise on how updating changes the issue following https://help.ubuntu.com/community/BIOSUpdate ? |
Request testing latest mainline kernel
In order to allow additional upstream mainline kernel developers to examine the issue, at your earliest convenience, could you please test the latest mainline kernel? Please keep in mind the following: |
Request testing drm-intel kernel
If the original reporter has reproduced the issue in the mainline kernel, and the issue is suspected to be drm-intel related, it is helpful for the reporter to provide results while testing it.
This issue is suspected to be drm-intel related. In order to allow additional drm-intel developers to examine this issue, at your earliest convenience, could you please test the latest drm-intel kernel? Please keep in mind the following: |
Request bisect
The next step is to fully commit bisect from the most recent kernel version that worked to the next kernel version that did not, in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? This article was written for folks who don't know anything about linux, so it's easy to follow. |
Request reverse bisect
The next step is to fully reverse commit bisect from the most recent kernel veresion followed by the next kernel version that worked, in order to identify the earliest good kernel commit, preceded immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ? This article was written for folks who don't know anything about linux, so it's easy to follow. |
Request submit to upstream
It is most helpful to upstream that the original reporter provide all the information necessary for an upstream developer to begin working on it (ex. regressions bisected, latest upstream kernel tested, call trace captured, etc.). Also, it is helpful to original reporters to advise them which maintainer(s) to send this to, and which mailing list to CC as it is not always obvious.
DRM Intel
The issue you are reporting is an upstream one. Could you please report this problem to Intel following their instructions via https://01.org/linuxgraphics/documentation/how-report-bugs? |
All others
The issue you are reporting is an upstream one. Could you please report this problem following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate mailing list? |
