The reason of this issue is the UFS device has a > little bit longer latency for NOP OUT response. It causes booting fail > because NOP OUT command is issued during initialization to check whether > the device transport protocol is ready or not. This issue is resolved by > releasing NOP_OUT_TIMEOUT value. Applied to 5.10/scsi-staging, thanks! -- Martin K. Petersen Oracle Linux Engineering
