Resending this because I want to make sure jung-uk Kim gets included in the future discussion. Sorry for the really delayed response. Yes, I am 100% sure I am booting with UEFI. And I don't seem to have any issues. Again, the only bug I still encounter is that occasionally X hangs and has to restart the driver. And if I look at the console, I get errors about "GPU not responding. Attempting to reset GPU", and so on. I don't know if it helps, but again, my CPU is an AMD A10-7860K (2016) model with onboard Radeon R7 graphics. If there's any other info I can provide, please let me know.
