Apple Wireless Trackpad "magicmouse" crashes kernel on multitouch

[Chad Miller]

This happens the same on my Thinkpad X301 (2777CTO) and my home desktop frankenstein machine.

Pair new Bluetooth APPL "Wireless Trackpad". Single finger clicks and drags do not seem to cause a problem. More than one finger gestures crashes either as: Hard hang with flashing keyboard light and no SysRq, Immediate reboot, or Delayed hang and X return to text console and freeze with no SysRq and no blinking.

It's hard to get a syslog. The only syslog messages I get appears to be a result of the hang but not near the cause. Attached as "syslog-hang-on-frankenstein.txt".

Attached video recordings of hangs and photos of oopsen.

Did this just start happening after a recent upgrade or update? It would be good to know if there was a prior release that did not have this bug.

Also, would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0].

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'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

This is new hardware to me, Joseph. I have no experience with other kernel versions with it. Will try upstream vanilla.

i experience also kernel crash on fedora 19 with such mouse. It won't help in ubuntu's case, but just to let you know 3.11 kernels are not better.

[Baif (baifcc)]

Same situation confirmed as following:

Apple Trackpad indeed crashes kernel 3.12.0-031200-generic on SAUCY.
But 3.11.0-12/3.11.0-14 seem to be good.

I have tried TRUSTY alpha1, either 3.12.0-6/3.12.0-7, both of them crashes with trackpad.

AND, I also test Apple MagicMouse, none of mentioned kernel crashes with it.......

The following threads have resolution for SAUCY with 3.11 kernels, BUT no for SAUTY with 3.12 nor TRUSTY with 3.12 (Haven't tried 3.13-rcx)

Baif, thank you for your comment. So your hardware may be tracked, could you please file a new report by executing the following in a terminal while booted into a Ubuntu repository kernel (not a mainline one) via:
ubuntu-bug linux

For more on this, please read the official Ubuntu documentation:
Ubuntu Bug Control and Ubuntu Bug Squad: https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue
Ubuntu Kernel Team: https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Filing_Kernel_Bug_reports
Ubuntu Community: https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette

When opening up the new report, please feel free to subscribe me to it.

Thank you for your understanding.

[Baif (baifcc)]

Sure I'll try to file a new report for this topic.

Chad Miller, would you mind to share few more. Do you have any chance to try Apple Magic Mouse, or try to name the track pad with MacOS?

One more to be added is that I found that Apple Magic Mouse in fact could be programmed to have its own "Device Name" with MacOS. But Apple Wireless Trackpad seems does NOT.

My Apple Magic Mouse has its "Device Named" named with it first paired with my MBP, but after that I failed to change the "Device Name". Meanwhile, I have never succeeded to name my Apple Wireless Trackpad with my MBP.

The fact is that, 8 out 10 times, the hci/lsinput/dbus/bluez/kernel etc found the "Device Name" of my trackpad is NULL, they took the Product name "" everywhere. Rarely, the hci/lsinput/dbuz/bluez/kernel report the "correct" "Device Name" as "Apple Wireless Trackpad".

And I think this "Device Name" in hci/lsinput causes troubles!!! Not only to kernel, but also version of KDE bluz wizard. If it can not pick the "Device Name" it would let you click "Next" Which is stupid. Thank god the KDE bluz integration works on Ubuntu, and there is bluetooth-agent you can use. Firing the bluetooth signal to Fedora 20, cause KDE Bluetooth help crashes

[Baif (baifcc)]

Correction: If it can not pick the "Device Name" it would NOT let you click "Next" Which is stupid.

[Baif (baifcc)]

I just bought a brand new Trackpad, and it has been named by firstly paired with MacOS. But it still crashes the SAUCY with 3.12 kernel from kernel PPA mainline.

[Chad Miller (cmiller)]

With updated BIOS from Lenovo, also crashed. Hard crash, no klogging of message. Photo attached.

[penalvch (penalvch)]

Chad Miller, thank you for updating your BIOS. Could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, please just make a comment to this.

If reproducible, could you also please test the latest upstream kernel via http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc7-trusty/ and advise to the results?

[penalvch (penalvch)]

Chad Miller, thank you for your comment. One may find it best to capture a kernel call trace following https://help.ubuntu.com/community/DebuggingSystemCrash , as the attachment https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1248287/+attachment/3942078/+files/log didn't have any useful information unfortunately.
