sounds like a kernel bug, try v4.2 mainline kernel

Sorry for the spam; appport-collect is segfaulting, but it looks like it updated correctly.

@penalvich: After bios update, the problem remains.
@tjaalton: It's not clear to me how to update to 4.2 on ubuntu 15.04

[penalvch (penalvch)]

Aaron Staley, you don't need to apport-collect more than once, or any further unless specifically requested to do so.

Despite this, is this still reproducible?

[penalvch (penalvch)]

Aaron Staley, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue.

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, Y, and Z are numbers corresponding to the kernel version.

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.

[Aaron Staley (astaley)]

Not seeing any crashes under latest kernel. ( 4.3.0-040300rc6-lowlatency). Thanks for the tip!

[penalvch (penalvch)]

Aaron Staley, the next step is to fully reverse commit bisect from kernel 3.19 to 4.3-rc6 in order to identify the last bad commit, followed immediately by the first good one. Once this commit has been identified, then it may be reviewed as a candidate for backporting into your release. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

Thank you for your understanding.
