Error initialising accelerometer DUAL250E

[Phill]

I'm fairly certain that the DUAL250E is the accelerometer on the Lenovo Yoga 300-11/BY.

I suspect there are two, one in the lid and one in the base, and they are needed to trigger auto rotate and disable the keyboard and touchpad in tablet mode. Without them these functions may be impossible.

Note that some people reported the lid giving off key codes for similar Lenovo tablets but that does not appear to be the case with this one running my current software. Not sure if this is relevant to the bug but I didn't want to dismiss the idea out of hand.

The expected functionality would of course be to perform auto-rotate and disable the keyboard/touchpad, but at this stage I'd settle for the accelerometer being usable as I understand this is not yet unplemented.

I trust ubuntu-bug attached the appropriate information, but here is the kern.log output just in case...

Phill, thank you for reporting this and helping make Ubuntu better.

In order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results.

Thank you for your understanding.

Updated the BIOS, no change, kernel log reports the same error.

```
$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
[sudo] password for phill:

```
That was an endeavour! I should have done it before installing Ubuntu. The machine has only 32GB of eMMC storage so dual booting is out, I only has 16GB USB sticks which Windows 8.1 would crash on boot, so I was left re-flashing back to Windows then back to Ubuntu.

Let me know if you have any other suggestions.

[penalvch (penalvch)]

Phill, the issue you are reporting is an upstream one. Could you please report this problem following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate mailing list (TO Wolfram Sang CC linux-i2c)?

Please provide a direct URL to your post to the mailing list when it becomes available so that it may be tracked.

Thank you for your understanding.
