[Samba] Linux Kernel crash on S390

[Agg Steve]

Hi,

I was hoping some one may be able to help with a problem I have.

If I try to modify/write to a share from a windows 2000 desktop (through
windows explorer or through command prompt) then Linux crashes with the
following error.
kernel BUG at fcntl.c:417!

I have no problems seeing the share on a windows 2000 PC and I have no
problems with the share (read or write) when accessing the share from a
Windows 95 machine. I have also tried mounting the share on a pc running red
hat linux with no problems.

My setup:

Suse Linux 7.2 running as a VM (release 2.3) guest on a G4 processor (not
officially supported for Suse 7.2 !)
Kernel 2.4.7
Samba 2.2.0 a
Windows 2000 SP2 desktop

Linux/Samba binaries installed from the Suse CD.

Relevant parts of my SMB.CONF

        workgroup = CIVIC
        netbios name = S390
        server string = Suse LINUX 7.2 running SAMBA
