Results may not be reliable. Haven't used any funky nfs options: CONFIG_NFS_FS=y CONFIG_NFS_V3=y # CONFIG_NFS_DIRECTIO is not set CONFIG_ROOT_NFS=y CONFIG_NFSD=m CONFIG_NFSD_V3=y # CONFIG_NFSD_TCP is not set CONFIG_SUNRPC=y CONFIG_LOCKD=y CONFIG_LOCKD_V4=y It is not related to the symlink fix, I reverted it, just to be sure. After reverting NFS_ALL, oopsing went away. Any ideas other then trying all patches one by one :-( Cheers, Hans-Peter
