Here is the updated info.

Steve French (samba team) made available a newer cifs version (1.48)
backported to old kernels:

http://lists.samba.org/archive/linux-cifs-client/2007-April/001898.html

Using this cifs code Jeff Layton (RH) has built some test kernels
after making appropriate adjustment for RHEL:

You can try the test kernel to see if the problems have been fixed, or
if you would rather not use any test kernel, you can just get the cifs
module compiled.  I have compiled a x86_64 version of cifs for CentOS
5 for my own use and confirmed it has eliminated the bug that causes
system crashes in kernel 2.6.18 (C5's default).
