Hi Adrian,

Could you please try latest drm-intel-nightly from cgit.freedesktop.org/drm-intel?

Also please boot your kernel with drm.debug=0xe and attach dmesg with complete information.

Please refer to https://01.org/linuxgraphics/documentation/how-report-bugs

Thanks,
Rodrigo.

v4.1-rc7 regresses SKL then? what version did you test that was working before? that'd also help narrow down the regression.

Thanks,

Hi Rodrigo,

Thanks for the info.

The issue (black screen) went away with the latest drm-intel-nightly.  But, lots of Call Trace messages are observed. Please find dmesg-drm-intel for details. 

Do you want me to close this bugzilla and open a new bugzilla for the Call Trace messages? Or, just keep this bugzilla? Kindly let me know.

Thanks in advance.

SKL is supported since kernel v4.3.

If the problem persists with latest kernels, please file a bug at the freedesktop.org bugzilla [1], referencing this bug. Thank you.
