[Samba] Revisiting SMB and SMP

Hi Samba List,
   I did a little sniffing around for issues between samba and SMP, but 
didn't seem to come across any that dealt with the behavior I'm seeing.

The general question is:  Does samba work correctly in an SMP 
environment?  Apparently OOB it doesn't...but is there a way to make it 

The specifics of my situation are as follows:
- Custom-built Debian Sarge kernel-2.6.8
   -- Support for 4 cpus (2 HT Xeons, which each appear as 2 cpus)
   -- samba is compiled-in on my most recent attempt

- When booting a non-SMP kernel, samba works flawlessly.

- When booting the SMP kernel, samba loses its ability to create or 
modify files, spitting out input/output errors, such as the following 

samus:/mnt/smb/file-serv/george# touch testfile
touch: setting times of `testfile': Input/output error

(names have been changed to protect the guilty)

Any help would be greatly appreciated, as I would enjoy being able to 
utilize the benefits of both SMP and SMB.
