I have no trouble with most CIFS mounts but one is causing my machine to freeze. I am executing the following command:

sudo mount -t cifs //servername/docs/ /mnt/servername -o user=name,domain=dname

The mount seems to connect properly and I am able to ls, cd, and so forth, a few times. After several cd and ls commands, however, my machine locks up hard and I have to reset with the power button. This is consistently reproducible from my laptop running 8.10, with smbfs version 2:3.2.3-lubuntu3.3.

I can connect to this resource using nautilus without problem. Here is a description of the server I am trying to connect to (I got this from tech support):

When you map servername now, you are actually mapping a pointer to a share on a storage device (the share is servername1\docs)

In Use Active Server Name servername1 Server Function Administrative Shares/Home Directories Service Tag [redacted] Server Role APPLIANCE-NAS Service Level 1 High Operating System Server Model NetApp 3050

The content on this device is served out using the recently deployed content management system (SiteCore) which runs on a pair of redundant Windows servers

Active Server Name servera and serverb Operating System Windows Enterprise Server 2003 Server Model Dell PowerEdge 2950

I assume there is a bug somewhere (nothing should cause a freeze) but I wonder how to narrow this down before reporting.

Any and all suggestions appreciated. Thanks.

I have excactly the same issue, and I've contributed to this bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=509428

I advise you to report the bug as well. I recently upgraded one of my laptops to 8.10, and it crashes hard once I enter a share on one of the netapp servers at my work. I cannot even shut it down anymore, and have to remove the battery. I can connect well to Debian servers. I still have laptops running 8.04, and they have no problem with the same netapp shares.

I would like to know if you also see the strange thing I see with the permissions in the share with 8.10 like I reported in the bug report. When you do an ls -la in the top level of the share, is it writable ?

I consider this a critical issue, as we will not replace our netapps easily, and I can imagine there are more companies using these :-).

So I also wonder what options do I have:

-Do a downgrade and install 8.04 (another weekend configuring) -Build a new kernel. Not prefered -Install more recent Samba (does that solve the issue ?) -Wait till 9.04 and hope it is solved -Use M$ windows XP for now -Something else ?

I cannot wait till April to get this solved, as I do have to do some work. I have the impression that the bug is not considered serious though, so that leaves me with the options of installing 8.04 or using XP. I hope somebody else has a better idea.

What would you do ?
