kernel + cifs = Send error in read

I upgraded kernels earlier this week by using's full src of 2.6.16-1 and my .config file from my old kernel. I'm not using modules and I compile all my known hardware staticly.

My previous kernel was 2.6.13-1. I've verified CIFS support was still set "on" in my .config file and tonight I recompiled again just to be sure.

I can still mount -t cifs //Server01/my_share /mnt/data -o user=me and I've been mounting/reading/writing fine in earlier kernels. I can see files listed but when I try to access the data I now get:

CIFS VFS: Send error in read = -13

I see these errors in dmesg and syslog. Any tips on how you would troubleshoot this?

Unfortunately smbfs mounting has never worked for me in any 2.6 kernel due to the

cli_negprot: SMB signing is mandatory and we have disabled it.
1391: protocol negotiation failed

type errors. I've seen this particular signing error in this forum alot but never a solid resolution when I had tried smbfs mounting. CIFS was the recommended fix and CIFS still works in 2.6.13 for me when I boot back to it.

When I went from 2.6.13 to 2.6.16 I copied my 2.6.13 .config into 2.6.16's tree and went at make menuconfig. Should that procedure work fine or did I maybe hose something in the config process?
