[Bug 659712] Re: New device name enumerated after suspend/resume cycle
Vaibhav, 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 following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc5
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
If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER
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.

Title:
New device name enumerated after suspend/resume cycle
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
On Thinkpad T61, the touchpad and trackpoint are enumerated using the
i8042 driver to be serio devices. In 2.6.32 series kernel from Lucid,
the trackpoint was always enumerated as serio2 after a resume and its
sysfs entry remained under /sys/devices/platform/i8042/serio1/serio2/.
With Maverick 2.6.35 kernel, after a resume a new device entry is
created and older lost. So from serio1/serio2, it changes to
serio1/serio3 after a resume, then to serio1/serio4 and so on. I set
parameters using sysfs.conf for trackpoint sensitivity/speed and those
are lost since a new device entry is created.
