GPU crash on NUC with i915

[Alexander List]

Setup:

Intel NUC, i915 graphics, two monitors, one connected with miniHDMI->HDMI cable, second with miniDP->HDMI cable.

Screen goes black, flickers back on, goes black again. Only resolution is to ssh into the machine and reboot.

Before rebooting, I got lots of these (about 106k lines) in syslog:

kernel: [404964.521324] [drm:hsw_unclaimed_reg_detect.isra.12 [i915]] *ERROR* Unclaimed register detected. Please use the i915.mmio_debug=1 to debug this problem.[drm:hsw_unclaimed_reg_detect.isra.12 [i915]] *ERROR* Unclaimed register detected. Please use the i915.mmio_debug=1 to debug this problem.

...then,

Thank you for taking the time to file a bug report on this issue.

However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request.

We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not.

You can update to the latest development kernel by simply running the following commands in a terminal window:

    sudo apt-get update
    sudo apt-get dist-upgrade

If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released.

If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging.

 Thank you for your help, we really do appreciate it.

This problem occured once in two months, and we are not aware of a way to trigger it. However, there is a clear indication that the bug is well known upstream, so it should be followed up with in Ubuntu as well.

upstream is closed WFM

time to close here, too?
