[Samba] SuSE8.0 and SAMBA crash

Wed Jun 12 09:09:02 GMT 2002

Hi all,
  We have been using SuSE7.2 and samba (client and server) without any
problems for a few months. Now, we migrated some workstations (samba
clients) to SuSE8.0 and we get segfaults while accessing files mounted
through samba. The segfault happens on the CLIENT side.

  Here is our network configuration:

    - SuSE7.2 server with default samba server package.
    - Few SuSE7.2 workstations with default samba client packages.
    - Few Windows2000 workstations.
    - Few SuSE8.0 workstations with default samba client packages.

  Every SuSE workstation is UP and has a default SuSE UP kernel
(2.4.4-4GB for 7.2 and 2.4.18-4GB for 8.0).

  Windows2000 and SuSE7.2 clients can access our server without any
problem.

  SuSE8.0 clients crashes (segfault) while accessing a mounted
directory. The crash happens at a random time (ie: doing a ls -lR in a
mounted directory causes a segfault at random).

  The SuSE8.0 workstations are Intel Pentium 4 1.8GHz with 256MB of ram.
I copied the output of lspci below:

  Here is the log I get:

  And here is the output of uname -a:

  Is there a patch or something I can apply to fix this problem?

  Thanks,
