SubjectIMAP through SSH tunnels stopped working in 2.6.35
From
Date
Hi,

I recently tried out 2.6.35-rc3 kernel (latest Linus's tree), where I
noticed that I couldn't access my IMAP accounts through ssh tunnel
anymore because connection timeouts. Things used to work in 2.6.34-rc7+.

I also tested with two wireless card: b43 and iwl3945, so it isn't
driver related issue.

I'm creating tunnel using: `ssh -L 10443:server:993 server`, and then
use imap client to connect localhost:10443.

Strace log of failing ssh tunnel:
