A Breakthrough... Sorta
I booted up with the installation DVD and went into "rescue mode". I then activated the volume group for the root filesystem, mounted root and chrooted so that I essentially have the same system as when I boot normally. The only difference is the kernel. I tried rsync and ssh for tests again and this time they worked. The kernel from the installation DVD is linux-2.6.28-11-generic and my normal kernel is linux-2.6.28-3-rt with SMP and RT optimizations.
So I used aptitude to install linux-2.6.28-11-generic kernel and headers and rebooted. The transfers now work. However, in the long run, this is not ideal since I need the RT optimizations for composing music and SMP optimizations wouldn't hurt for audio and video work. So now I need to see if I can narrow the problem down a bit more to see if I can file a bug report. Anyone know how to do that in Ubuntu land?

switch_root
SWITCH_ROOT(8) System Administration SWITCH_ROOT(8)
NAME
switch_root - switch to another filesystem as the root of the mount tree
SYNOPSIS
switch_root [-hV]
switch_root newroot init [arg...]
DESCRIPTION
switch_root moves already mounted /proc, /dev, /sys and /run to newroot and makes newroot the new root filesystem and starts init process.
WARNING: switch_root removes recursively all files and directories on the current root filesystem.
OPTIONS
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
RETURN VALUE
switch_root returns 0 on success and 1 on failure.
NOTES
switch_root will fail to function if newroot is not the root of a mount. If you want to switch root into a directory that does not meet
this requirement then you can first use a bind-mounting trick to turn any directory into a mount point:
mount --bind $DIR $DIR
SEE ALSO
chroot(2), init(8), mkinitrd(8), mount(8)

AVAILABILITY
The switch_root command is part of the util-linux package and is available from https://www.kernel.org/pub/linux/utils/util-linux/.
