Updating kernel on SLE 11 SP1 breaks CIFS

This document (7006684) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 11 Service Pack 1
SUSE Linux Enterprise Desktop 11 Service Pack 1


Updating the kernel to version causes the following problem.
The updated machine has a CIFS share mounted.
Browsing the mount point via the command line or GUI is fine, but as soon as a file is read or copied, the machine hangs. To recover from this condition a reboot is required.
The problem did not exist prior to updating the kernel.

This is caused by a change introduced the Linux kernel version


Downgrading the kernel resolves the problem.
SUSE has fixed the issue in kernel version released in September 2010 and later versions.
From the changelog of kernel :
* Wed Aug 04 2010
- patches.fixes/cifs-fix-vfs-busy-inode-errors: Revert the commit that fixes
  page refcount leak which is not required but causes hangs (bnc#627518).
