Now my mouse doesn't work, and oddly the scroll on my synaptics touchpad got broken. I'm not sure if I can reproduce this issue.

Sorry, not sure how that happened. I'm uploading now.

[Joseph Salisbury (jsalisbury)]

Was this a one time event, or can you reproduce this?

Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the others). 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 by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.2-rc1 fixed and issue, the tag would be: 'kernel-fixed-upstream-v3.2-rc1'.

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

Thanks in advance.

[James M. Leddy (jm-leddy)]

This was a one time event. I was hoping that someone would be able to find the bug based on the traceback based on it being a WARN leading to a null pointer. I don't have a consistent reproducer, but I expect this to be a bug upstream unless someone else had fixed it. If it happens again I'll let you know and install mainline.

[James M. Leddy (jm-leddy)]

Okay, I may be able to reliably reproduce this by rapidly turning on and off the kill switch while moving the mouse. I just had it happen again and now my mouse doesn't work at all. In the process I learned that the kernel somehow gracefully fails from null pointer dereference now.

Same problem here, also happens occasionally on resume from standby. Moving the mouse "too soon" after wake appears to kick off this problem and break my bluetooth mouse permanently until reboot.

[Keng-Yu Lin (lexical)]

a few discussion in the thread: http://www.spinics.net/lists/linux-bluetooth/msg15564.html

The patch didn't get itself upstream but gives some hint on the cause as described in: http://www.spinics.net/lists/linux-bluetooth/msg15598.html

Hi Keng-Yu,

Thanks for the info, I hope this bug works itself out upstream.

I still see it under 3.5.0-18-generic @ Quantal.

[Øyvind Stegard (oyvindstegard)]

Confirm this on system just recently upgraded to Ubuntu 12.10. The bug hits on resume from suspend, and it makes bluetooth unusable.

[Achim Behrens (k1l)]

i have the same with my Bluetooth Keyboard. When it falls in Standby itself, after not typing for some time, i cant use it. Restarting Bluetooth Deamon or turn it on and of with panel indicator doesnt help.

Using 12.10 and cant reproduce on purpose, but does happen after some time nearly every day.

[Christian Schürer-Waldheim (quincunx)]

I had the same problems with 12.10 (using an Apple Magic Mouse). I found some mailinglist discussions by developers about this problem and there should be changes in kernel 3.5 addressing these issues.

As the kernel in 12.10 obviously does not have these patches, I tried the 3.7 kernel from the mainline-kernel-ppa (package name indicates that it is for raring, but the kernel works on quantal, too). Using this kernel, the problem is fixed for me.

[Christian Schürer-Waldheim (quincunx)]

This problem still occurs occasionally with the raring kernel (3.8.0-13). I didn't see this problem with the mainline kernel 3.7.

[Trunone (trunone)]

still have same bug with 3.8.0-14

Try the mainline kernel (http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8.6-raring/) - it works for me.

[Andrew de los Reyes (andrew-launchpad-w)]

Hey folks, we're still seeing this on Chrome OS. We have a 100% reliable repro case:

- have Apple Magic Trackpad connected and working
- sleep/wake
- immediately click/rub fingers on trackpad
- panic!

We're tracking this at https://code.google.com/p/chromium/issues/detail?id=228937

We're planning to put in the hack listed, since it works for us, but we would like to let others know that, as far as we can see, this issue persists. If there is a fix not linked from here, we're eager to find it!

We are using the 3.8 bluetooth stack with a 3.4 kernel.

[Christian Schürer-Waldheim (quincunx)]

The latest kernel in raring could have a fix for this problem:

[Christian Schürer-Waldheim (quincunx)]

Just had this problem again, even with latest raring kernel (3.8.0-19). I think this problem is related to the power info of HID devices. Right before the problem occurs there is a "driver failed to report capacity property" message for this device (Apple magic mouse):

[penalvch (penalvch)]

James M. Leddy, 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 linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

[Ilya Murav'jov (muravjov-il)]

Have this bug with my Bluetooth mouse, aftere resume-wake and mouse activity. Workaround: before mouse activity turn off bluetooth connection via GUI, so bluetooth status icon does not have small padlock in it.

I tested issue with trusty and vivid kernels.
