[Bug 1443764] Re: Black screen of death: system suddenly stopped working soon after upgrade to kernel


pramathesh ambasta, could you please test the latest upstream kernel
available from the very top line at the top of the page (the release
names are irrelevant for testing, and please do not test the daily
folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will
allow additional upstream developers to examine the issue.

If the test 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 bug 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:

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:

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.

  Black screen of death: system suddenly stopped working soon after
  upgrade to kernel

Status in linux package in Ubuntu:

Bug description:
  I update the kernel images from update-manager this morning on my
  Ubuntu 14.10 system running on my laptop.

  I had started backintime-gnome to take a backup of my home directory
  on an external seagate drive connected to a 4 port USB hub. This is
  something I do almost daily

  I was editing a desktop shortcut on nano when suddenly I saw a black
  screen with a lot of dumps and messages from the kernel (or what
  seemed like the kernel). The screen was frozen - no mouse movement or
  keyboard movement would restore it. I had to force a restart using the
  power button.

  This is the first time I have encountered something like this.
