We have a windows 2003 server with a directory shared. I connect to it from linux (Ubuntu 12.04) using CIFS. Once mounted, I can read/write files, list files, et cetera from the linux box. However, if I run "find . -name \*txt" and hit ctrl-c before the find command finishes then the mount immediately fails (the find command takes about 15 minutes to complete on this particular file system). Not only that, once the mount fails I can't successfully remount the drive without rebooting the linux box. This makes me think a kernel bug is in play.... Occasionally using lsof or fuser I can find a process that is keeping the mount alive, kill it, and remount the filesystem without rebooting. However, this is rare.
Perhaps I'm just missing some setting to CIFS, but I can't figure it out. I know what you are thinking "Use the google, Luke" which I have tried. However, I get about 5000 hits for "I kan't mount my Windozes on my linux, kan u give m3 teh codez pleaze" which is almost, but not quite my issue. Anyhow, /etc/fstab contains: //server/All_proj /server/all_proj cifs sec=ntlmv2i,iocharset=utf8,uid=perry,credentials=/home/me/.smbcred,noauto,filemode=0777,dir_mode=0777,_netdev,gid=5000 0 0 Around the time the mount fails, I see this in /var/log/syslog: Dec 13 10:40:35 chinstrap kernel: [ 2412.028311] CIFS VFS: Unexpected SMB signature Dec 13 10:40:35 chinstrap kernel: [ 2412.028318] CIFS VFS: Send error in Close = -13 Dec 13 10:40:35 chinstrap kernel: [ 2412.028558] CIFS VFS: Unexpected SMB signature Dec 13 10:40:35 chinstrap kernel: [ 2412.028886] CIFS VFS: Unexpected SMB signature Dec 13 10:40:35 chinstrap kernel: [ 2412.029395] CIFS VFS: Unexpected SMB signature .... I also see the following in /var/log/kern.log Dec 13 10:01:29 chinstrap kernel: [ 66.567463] CIFS VFS: default security mechanism requested.

So....I know there must be somewhere to report this as a bug and beg for help, but I have no idea where? Do I go to the Ubuntu folks at Canonical? To the Linux kernel team? Here? Help please!
