sshd issues with 2.6.38-rc1

[john stultz <johnstul@us.ibm.com>]

Just an FYI: I'm having problems sshing to a machine I just updated to
2.6.38-rc1. The machine is running Ubuntu 10.10, and and 2.6.37 with the
same config doesn't seem to have a problem.

The box is always pingable. But when I ssh in from a client, it just
hangs before authenticating. 

In the dmesg, on both kernels, I see:
sshd (1852): /proc/1852/oom_adj is deprecated, please
use /proc/1852/oom_score_adj instead.

Using ssh -vvv I get all the way to:

debug1: SSH2_MSG_NEWKEYS received
debug1: Roaming not allowed by server
debug1: SSH2_MSG_SERVICE_REQUEST sent
debug2: service_accept: ssh-userauth
debug1: SSH2_MSG_SERVICE_ACCEPT received
debug2: key: <blah blah>

With ps, I see:
root  ...  Ss ...  sshd: [accepted]
sshd  ...  S  ...  sshd: [net]


Anyone have a clue? Otherwise I'll try bisecting it down.

thanks
