mouse freezes on ThinkPad Edge 11

[chrysn]

on the thinkpad edge 11 described by the attachments, the touch panel freezes at indeterminate intervals for several seconds.

the x log reports that the "TouchPad [...] lost sync at byte [...]".

the mouse seems not to show the described behavior in the kernel i installed (linux-headers-3.4.0-030400rc2-generic 3.4.0-030400rc2.201204072235)

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.4kernel[1] (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 other tags). 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'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

the mouse seems not to show the described behavior in the kernel i installed (linux-headers-3.4.0-030400rc2-generic 3.4.0-030400rc2.201204072235).

as the behavior by itself occurs without an observable pattern, i could just have been (un?)lucky in the last hours, but the problem seems to have been resolved by the upgrade.

Marking Triaged as mainline tested.

[penalvch (penalvch)]

Does not affect mainline.

[chrysn (chrysn)]

for further tracking and bisection, the problem was still present after an upgrade to precise with a 3.2.0-23-generic kernel. using v3.4-rc6-precise (3.4.0-030400rc6-generic_3.4.0-030400rc6.201205061835) again seems to fix it.

[chrysn (chrysn)]

the problem resurfaced, still using the 3.4.0-030400rc6-generic kernel -- obviously, the new kernel version alone didn't fix it.

from a subjective judgement, the glitches are shorter; i don't have a tool to accurately measure it, though.

[penalvch (penalvch)]

chrysn, could you please provide the information following https://wiki.ubuntu.com/DebuggingTouchpadDetection#In_case_at_least_one_of_Touchpad_features_works_but_does_not_work_correctly_and_as_expected ?
