[Samba] Samba 3.2.3 + Ubuntu 8.10 smbd panic

[Hervey Wilson]

If this is the wrong list, apologies and redirect happily accepted :-)

Following an upgrade of my AD joined Ubuntu 8.04LTS / Samba 3.0.28  
server to Ubuntu 8.10 / Samba 3.2.3 smbd crashes on all connection  
attempts from clients. Domain controller is Windows 2008 Enterprise,  
winbindd appears to be functioning, wbinfo is good, getent is good,  
although there are several messages referring to not being able to get  
the network address for the KDC for the realm. After trying to prune  
smb.conf back to something minimal, I'm stuck.

Below is the panic trace at debug level 5 from the log for one of the  
clients that triggers the crash:

Any advice that anyone can offer for determining the root cause of, or  
fixing, the panic will be much appreciated!
