Hubert Hesse, in order to allow additional upstream developers to examine the
issue, at your earliest convenience, could you please test the latest upstream
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 upstream kernel, please comment on which kernel version
specifically you tested. If this issue is fixed 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 mainline kernel does not fix the issue, 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.
Once testing of the latest upstream kernel is complete, please mark this
report's Status as Confirmed. Please let us know your results.
Thank you for your understanding.

Title:

Status in linux package in Ubuntu:
Incomplete
Bug description:
Upgraded linux-image-extra-4.2.0-30-generic I see graphic glitches,
looks like the graphic buffer gets screwed up
- funny repetition's patterns (back in time glitches)
- black screen (<1sec)
- graphic errors
I can influence the severity of the issue with switching windows and
using certain programs, e.g. Google Maps in chrome causes this issue
reproducibly
