I hadn't needed the OBH FullBackup restore since ages. But today I tried it and it resulted in regular crashes. At the moment, I don't even have the image in multiboot, as I used to, but now it's in flash. The FullBackup is performed on a daily basis on the NAS and the file is correctly created. I also tried, to be sure, to move the FullBackup from NAS to internal HDD and to modify the configuration accordingly, but it was the same. So, the NAS is not responsible. Attached there's the crashlog.
