plane A assertion failure (expected on, current off) on Intel NUC 5i5RYH

[Alexander List]

Getting assertion failures:

[ 9925.287976] plane A assertion failure (expected on, current off)

Around the same time, WiFi connections drop. I cannot prove the two problems are related, but I don't have WiFi issues on other devices.

I have two identical screens connected, one via HDMI, one via DP

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Sergey Alexandrov (alexandrov88)]

I get the same error when waking up from suspend. Have two monitors (HDMI, DVI) connected through Lenovo docking station.

Alexander List, thank you for reporting this and helping make Ubuntu better. As per https://downloadcenter.intel.com/search?keyword=NUC5i5RY an update to your computer's buggy and outdated BIOS is available (0350). 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 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, and the information above is provided, then please mark this report Status Confirmed. Otherwise, please mark this as Invalid.

Thank you for your understanding.
