Relevant bits from the config are: CONFIG_NFS_FS=y CONFIG_NFS_V2=y CONFIG_NFS_V3=y # CONFIG_NFS_V3_ACL is not set # CONFIG_NFS_V4 is not set # CONFIG_NFS_SWAP is not set CONFIG_ROOT_NFS=y CONFIG_NFS_FSCACHE=y # CONFIG_NFSD is not set CONFIG_NFS_COMMON=y Anything else I can provide? I could bisect the issue if that helps.
