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


pramathesh ambasta, thank you for reporting this and helping make Ubuntu
better. As per
an update to your computer's buggy and outdated BIOS is available
(1.09). If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

If it doesn't, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

For more on BIOS updates and linux, please see

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, and the information above is provided, then
please mark this report Status Confirmed.

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.
