I just ran into a 12.04.03 client, and it does have the problem.
Here's the dmesg output:
[ 3122.368038] INFO: task nautilus:2352 blocked for more than 120 seconds.
[ 3122.368042] echo 0 /proc/sys/kernel/hung_task_timeout_secs disables this

Ted Cabeen, thank you for your response. Would it be terribly
inconvenient to test if a 12.04.03 client works with your 12.04.03
server? This would help narrow down if the issue is client, or server.
Also, regarding your testing
Hmmm. Hard to say. The server was at 12.04.02 when I took over
management of the systems, and I upgraded the clients to 13.04 and the
server to 12.04.03 at about the same time, so it's hard to disentangle
which change caused the problem. I certainly had 12.04.02/12.04.02
client/server systems
Ted Cabeen, just to clarify, the last working client/server combination
was 12.04.03/12.04.03?
