Apologies for the delay - I haven't been using this system as much recently. The problem seems better with this build, but not eliminated. I now usually only lose one display at a time, and not nearly so frequently. The system will typically be OK for >24 hours, but once it starts the symptom, it then reoccurs about once per hour. The original kernel debug messages are gone, but I'm seeing: [344312.224123] [drm:asle_work [i915]] bclp = 0x8000000c [344312.224138] [drm:asle_work [i915]] updating opregion backlight 12/255 [344341.776561] [drm:asle_work [i915]] bclp = 0x80000019 [344341.776577] [drm:asle_work [i915]] updating opregion backlight 25/255 which I *think* are associated with the screen flashes. The system is a desktop with two 4k monitors.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
