No, there isn't anything showing up in dmesg.  Here is the samba version 
info:

[root at test ~]# rpm -qa samba\*
samba-client-3.0.28-1.el5_2.2
samba-3.0.28-1.el5_2.2
samba-common-3.0.28-1.el5_2.2
samba-swat-3.0.28-1.el5_2.2

Please let me know if there is a newer samba version I should be trying.

Thanks,
