[Bug 1397694] Re: System lockups with utopic kernel


Max Bowsher, thank you for reporting this and helping make Ubuntu better. As per http://www.dell.com/support/home/us/en/19/product-support/product/precision-t1700-workstation/drivers an update to your BIOS is available (A10). 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, then please mark this report Status Confirmed.

Thank you for your understanding.

  System lockups with utopic kernel

Status in linux package in Ubuntu:

Bug description:
  Since upgrading to utopic, I've been experiencing occasional system
  lockups - when this occurs, nothing at all is responsive including the
  mouse pointer and Alt-SysRq combinations.

  Lockups only occur infrequently - perhaps once every day or two days -
  so testing this is going to be slow and problematic.

  So far, rolling back to the trusty kernel seems to have fixed it, so
  it seems unlikely to be a hardware problem.

  I'm going to reboot into http://kernel.ubuntu.com/~kernel-
  ppa/mainline/v3.17.4-vivid/ now and run with that for a few days.
