Thanks a lot for testing! The problem with PMP CBS is my fault, I made a mistake when creating V4. The btrfs bug seems to be unrelated, even though it seems very bad. It is good that you have UART so you could see what was going on. Perhaps you could test on v7.0 (hopefully btrfs is more stable here) + v5 of this patch series (once I've sent it out). I'm sorry for my mistake... hopefully it will not go beyond v5. Kind regards, Niklas
