I'm running an T450s with 2 external DELL monitors, one 24" and a DELL 27", both are connected by Displayport.
After locking the desktop by windows+L key and returning after some time (minutes) the 27" DELL isn't working anymore and i have to reconfigure the whole display settings, the dmesg output bring up the following lines: … [19707.593875] [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!
