[bcm5974] Apple touchpad fails to respond, dmesg contains multiple mesages of form: bcm5974: bad trackpad package, length: 8

[Gerry Boland]

Have Apple Macbook pro 8,1. With Trusty devel, occasionally (i.e. twice in the last 3 weeks) my trackpad completely stopped functioning. From then on, dmesg is full of these messages:
bcm5974: bad trackpad package, length: 8

WORKAROUND: Remove and re-load bcm5974.

Gerry Boland, 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? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

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

apport-collect -p xorg-server REPLACE-WITH-BUG-NUMBER

Thank you for your understanding.

This is still an issue on a macbook pro 8,1 and its touchpad (not a very recent machine, but could happen on other machines with the same touchpad). I'll add apport information

Status changed to 'Confirmed' because the bug affects multiple users.

[penalvch (penalvch)]

Gerry Boland / Stefan Bethge, 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 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 mainline kernel, please comment on which kernel version specifically you tested. If this issue is not reproducible 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 issue is reproducible with the mainline kernel, 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.

It is most helpful that after testing of the latest mainline kernel is complete, you mark this report Status Confirmed.

Lastly, to keep this issue relevant to upstream, please continue to test the latest mainline kernel as it becomes available.

Thank you for your help.

[Stefan Bethge (kjyv)]

The issue is still happening with upstream kernel, tags added.

[penalvch (penalvch)]

Stefan Bethge, 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 Henrik Rydberg, and Dmitry Torokhov CC linux-input)?

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 help.

[Gerry Boland (gerboland)]

Hardware died on me, sorry I cannot test this any more.
