My setup is as follows:
D-Link DNS-323 <----> Linksys RVS4000 <----> PC running Windows XP Pro
The ethernet chip on my PC is a "Marvell Yukon 88E8056 Gigabit Ethernet".
The Linksys router has four gigabit ethernet ports.
When I enable 9000-byte jumbo frames on all devices, I fail to connect from Windows to the DNS-323 web interface.
My observations with frame sizes are as follows:
DNS-323 Linksys Windows Web server connect
------- ------- ------- ------------------
9000 9014 1514 OK
9000 9014 4088 OK
9000 9014 9014 Fail
The Yukon chip driver in Windows only gives me the above three options for frame size.
The symptom of the failure is: Browser displays "Waiting for Dlink-NAS..." forever.
I have tried both IE and Firefox.
Even though I cannot reach the web interface, file access (via windows drive mapping) works fine.

Disclaimer: I haven't used the jumbo frame feature on the DNS-323, so I'm just replying in a generic sense.
When you enable jumbo frames, you are essentially modifying the MTU. When your browser communicates with the DNS-323 web server, the client and the server must negotiate a sensible MTU. Mismatches are usually communicated (and then resolved) via ICMP messages. However, the web server may be blocking ICMP messages, meaning that a proper MTU can never be negotiated.
Now when you transfer files, you are using Samba, which has nothing to do with the web server.
So my guess is that somebody is dropping ICMP messages along the way... Very wild guess though.

Are you still able to transfer files in this configuration?

Yes.

I am getting the same issue with my DNS323. DNS323 supports jumbo frame so why can't the UI support jumbo frame as well? There has not been a firmware updates for ages and I think the Dlink support really sucks.

If you have the SAME issue, then chances are your router only supports jumbo frame upto a 4K frame size - I have no problem running jumbo frame up to 9k - but then I'm not using that router.
You can, very easily, verify that the router is the cause of the problem (or eliminate it) - set suitable static ip addresses on the NAS and the PC and then connect them directly to one another - if you can now communicate upto the maximum frame size, the problem was the device removed from the connection, and conversely, if the problem remains, then it's either the PC or the NAS.
