The fstab entry was like this: \\servername\resource /mountpoint cifs domain=MYDOMAIN,credentials=/etc/fstabcred,rw,noauto,iocharset=utf8,uid=username,gid=group,sockopt=TCP_NODELAY,users,file_mode=0640,dir_mode=0750,relatime 0 0 I looked at cifs options, and tried to add "sign" and "sec=ntlmv2i". It made no difference. Still failure with 2.6.39, and mounting with these new options works fine with 2.6.38 Helge Hafting
