My NAS is installed with 918+ 6.2.X DSM on 1.04b loader included drivers updates for NIC card that have been running for 2 months. I always gotten into trouble to boot it successfully into DSM. It will stop at the usual screen below then it will change to another screen as shown below on 2nd photo. Always need to try reboot few times to get into DSM. What could be the problem? Thanks!
