Hello all.
I got the exactly same problem, HDMI CEC disabled do not matter is my experience..
I have tried atleast a dusin images the last two years, also with multibot, an so on.
Sometimes it run for hours, sometimes for days, sometimes for weeks before it freezes.
I changed to Japhar sim, but to no avail, same freezing.. :-(.

Which image are you using,
Clone hardware is different from Original, it was an Original DM900UHD problem (Motherboard dies, no communication from CPU), but never seen a report about the Original DM920UHD or the Clone DM900UHD.
Look instead into the image and/or plugin you would have installed that would cause such freeze (related to network communication RJ45 or PSU that doesnt supply the 5 Amp or the Softcam as seenin other boxes as the reason of freezes) and driver of the image in use (exact date of the real driver as the one shown on the GUI is not valid if the bcm ko file was replaced for patching the image).
The dead DM900UHD seems to be mixed to this software freeze problem... check what freeze, check if RC works, check if you can connect to box, etc.
I had the experience just yesterday on an original DM900UHD of a freeze, oscam wasnt accessible as a server but was still communicating as a client with the other box and was in the facts alive...
This is related to software/plugins/drivers, and I never had any freeze/stop if my two DM900UHD clone with the OpenPLi 7.2star image in 2 years with latest and updated Japhar drivers.
