[Bug 1548521] Re: kernel BUG at /build/linux-tSJmM_/linux-4.4.0/drivers/gpu/drm/i915/intel_display.c:10243!


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

As per http://esupport.sony.com/US/p/model-
an update to your computer's buggy, insecure, and outdated BIOS is
available (R0174J3). 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

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

Also, 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 Confirmed.

If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.
