        Regression: Yes


I have an ASUS M3A78 Pro motherboard (AMD64, RS780 chipset) with onboard
Realtek 8169. Normally the ethernet connection comes up quickly, including with
kernel 2.6.37-git7. With kernel 2.6.37-git9, I get the following in dmesg:

$ dmesg|grep eth0
[    0.878911] r8169 0000:02:00.0: eth0: RTL8168c/8111c at 0xffffc9000007a000,
00:23:54:5e:5d:d5, XID 1c4000c0 IRQ 40
[   11.156602] r8169 0000:02:00.0: eth0: link down
[   11.156639] r8169 0000:02:00.0: eth0: link down
[   11.157333] ADDRCONF(NETDEV_UP): eth0: link is not ready
[   12.780948] r8169 0000:02:00.0: eth0: link up
[   12.783051] ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

At this stage I can connect to the internet with HTTP/HTTPS but a telnet-ssl
<address-of-this-machine> or telnet-ssl from another machine to this one fails
at the telnet negotiation stage. telnet-ssl from this machine to another works.

Which is being reverted.
