[Bug 1540553] Re: task Xorg:1042 blocked for more than 120 seconds in schedule+0x37/0x80

 

bp, thank you for reporting this and helping make Ubuntu better.

As per http://www.dell.com/support/home/us/en/19/product-
support/product/latitude-e7250-ultrabook/drivers/advanced an update to
your computer's buggy and outdated BIOS is available (A09). If you
update to this following https://help.ubuntu.com/community/BIOSUpdate
does it change anything?

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

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, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status New. If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

Title:
  task Xorg:1042 blocked for more than 120 seconds in schedule+0x37/0x80

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  Since system updates on or after Thursday 28th, I have been
  experiencing complete system freezes when attempting to do tasks such
  as opening a menu or a window. Compiz manages to draw a shadow around
  the new window, then everything freezes:

  * You can SSH into the machine normally
  * Audio and network work fine
  * You can move the mouse cursor around
  * SysRq-REISUB works

  Everything else doesn't:

  * Clicking
  * Typing
  * Ctrl-Alt-Fn
  * Ctrl-Alt-Backspace (after having enabled it)
  * Killing Xorg
  * Occasionally, killing lightdm/compiz/etc.

  This has happened both with Unity and Cinnamon, so compiz and friends
  are not to blame.

  Xorg.org complains it is the victim:

  All the kernel knows is XOrg isn't responding. Not even kill -9 will
  make it budge.

  The only things I know about reproducing is:

  * It happens after 5pm
  * It most often appens immediately after a right click
  * Somehow, apt-get remove xserver-xorg-video-intel:amd64 was a no-op
  * It started happening after this set of updates:
