[oneric] acpi event is not detected in Oneric

[3ntix]

I've a Clevo M720 notebook rebranded as Santech T45. All the previous ubuntu releases support laptop hotkey without extra set up, but the last release seems that broke the support of them.
Almost all the acpi event are disappear. In particular, I notice that are not processor recognized:
- the ac_adapter plug and unplug
- battery charging/discharging event
- suspend button*
- backlight hotkey event*
- low power mode button*
- lid open/close

The bug is reproducible booting the laptop with a kubuntu 11.04 live. Using acpi_event command I've saved the output for low power mode button, backlight up and down and suspend button:

On the other hand, in kubuntu 11.10 there are no output at all.

3ntix, thank you for reporting this and helping make Ubuntu better. 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/ .

If it remains an issue, could you run the following command in the development release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.

[Expired for linux (Ubuntu) because there has been no activity for 60 days.]

[3ntix (francesco-3ntini)]

At the end I've try the last ubuntu release (in true, K-ubuntu). The bug is still present.

When I've time I'll try the last kernel.

I've installed the lastest mainline kernel, precisely "v3.5-rc4-quantal".
This doesn't change the things, the acpi event doesn't work in the last ubuntu releases.

Now I will do a new appoprt-collect when running with the mainline kernel

[3ntix (francesco-3ntini)]

Update: I'm not able to do an apport-collect with the upstream kernel.

[penalvch (penalvch)]

3ntix, thank you for testing the mainline kernel. As for apport-collecting the mainline, it will not let you do this by design. Despite this, we have the collect you performed from Precise so that will be fine.
Regarding this report, it seems this is a regression. You noted the earliest version this problem was reproducible in was Natty. Does an earlier release exist where this problem did not occur?

[3ntix (francesco-3ntini)]

Almost "all" ubuntu from 11.04 (Natty) and older does NOT have the but, all acpi event are recognized correctly.
From ubuntu 11.10 the bug appears, acpi event disappears at all. From 11.10 an next releases I've try some solution like updating acpi_support package or updating the kernel of future release but nothing happen.

The next think I'll try is to try other live distribution in order to understand if this bug is due to some "ubuntu personalization" or it is a kernel bug that affect all distribution.

If it is useful, I can do an apport-collect from a natty live where the acpi event are working right.

[penalvch (penalvch)]

3ntix, no need to run apport-collect from natty at this time. The next step is to perform a kernel bisect, from natty to oneiric, in order to identify the commit which caused the regression. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

[3ntix (francesco-3ntini)]

I've try to bisect the kernel but I've encountered some problem. I'll explain. The last know working kernel is last in ubuntu natty, 2.6.38-15 whereas the first not working kernel is the first one in oneiric, version 3.0.0-12, both kernel tested in a fresh ubuntu installation and also installed under a ubuntu precise.

As natty kernels are all working, I've try to bisect oneiric kernel but the commit between 2.6.38 to 3.0.0 thought 2.6.39 cause some issue in compiling.

Compiling problem happen also if I'm trying to bisect the linux vanilla kernel repository.

I've finished my knowing on kernel compiling and I've no idea how bisect kernels in the middle of two ubuntu releases. Any suggestion?

[penalvch (penalvch)]

3ntix, thank you for your efforts. The way to maximize the narrowness between problematic kernels, before bisecting commits, is to check against the published kernels in Oneiric https://launchpad.net/ubuntu/oneiric/+source/linux . As per this website, the following kernels overlap your testing space:
2.6.38-8.42
2.6.39-0.5
2.6.39-1.6
2.6.39-2.7
2.6.39-2.8
2.6.39-3.9
2.6.39-3.10
3.0-0.1

I would test each one until you have the problematic kernel immediately preceding the kernel that works. Then retool for bisecting commits between these two kernels.

[3ntix (francesco-3ntini)]

Status: I've download and compiled some of them. The results is:
2.6.38-8.42 ACPI work
2.6.39-0.5 ACPI DON'T work
2.6.39-1.6 ACPI DON'T work
2.6.39-2.7 not try
2.6.39-2.8 ACPI DON'T work
2.6.39-3.9 not try
2.6.39-3.10 not try
3.0-0.1 not try

Now? Bisect vanilla kernel tree or oneiric kernel tree?

[penalvch (penalvch)]

3ntix, I would pull down the Oneiric repository and chop through commits between:
2.6.38-8.42 ACPI work
2.6.39-0.5 ACPI DON'T work

[3ntix (francesco-3ntini)]

WOW, It takes 13 kernel compiling but it worth it!

[penalvch (penalvch)]

3ntix, now that the mainline was tested and the kernel bisected, the next step is to send it upstream. Hence, it would be nice if somebody having it could send the bug to the developers of the software by following the instructions _VERBATIM_ at https://wiki.ubuntu.com/Bugs/Upstream/kernel . If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about the status. Thanks in advance.

[madbiologist (me-again)]

A fix for this issue has been released upstream in kernel 3.7-rc1 and in kernel 3.6.3.

[Julian Wiedmann (jwiedmann)]

3ntix,

The required patches [0] have also landed in Precise (3.2.0-34.53) and Quantal (3.5.0-20.31).
Could you please test the latest kernel in -updates and confirm that this bug is fixed? Thanks.
