Linux – Files showing in smbclient but not smbmount

I have a samba folder that I try and access through smbclient, and I can browse it just fine. However, mounting it through smbmount, all the folders under the share are empty. I can list the folders directly under the share fine, but they all appear empty.

smbclient:

# smbclient //server/share -U username -W workgroup password

smbmount

# sudo smbmount //server/share mntpoint -o user=username,workgroup=workgroup,password=password

I have also tried with domain=workgroup instead of workgroup, both give the same result. No error messages, everything mounts fine, but all the folders under mntpoint are empty, despite the same folders being non-empty when using smbclient.

Are these using different libraries? How can I debug the error?

Additionally, if I try to mount //server/share/folder, doing an ls results in a segmentation fault. Using dmesg I find:

kernel BUG at /build/buildd/linux-2.6.28/fs/cifs/cifs_dfs_ref.c:315!

Using a credentials file, I first get empty dirs, then Resource temporarily unavailable. In my dmesg I see the following output:

CIFS VFS: compose_mount_options: Failed to resolve server part of \\srv\share to IP: -11
