[Bug 604314] Re: Kernel deadlock when running programs from aufs over squashfs

I didn't try to disable nbd-proxy, and add the --persist option to nbd-
client, but i switched to nfs+aufs on thin client. The situatuion is
same. If thin client plugged into server's switch - it works perfectly,
but in next switches thin client aren't boot. Nevertheless thin clients
in same network topology (couple of switches) are boot perfectly with
LTSP on ubuntu 9.10 and early. Problem appears only on LTSP of 10.04
(ku|edu|xu)buntu version.
