We're experiencing this too, here's a report from the tech that builds our LTSP servers which includes the network equipment we're using. Applying the patch (disabling nbd-proxy) doesn't completely solve things for us. We had none of these problems on 9.04.
======= When 2 or more switches are between client and server a failure to boot occurs before launching LDM about %50 of the time. The frequency of the failure to boot is reduced by being connected to the server with only one intermediate switch but does not go away completely. The following bugs seem to reference the same problem and indicate that it is nbd-proxy that is falling down during the boot process. https://bugs.launchpad.net/ubuntu/+source/ltsp/+bug/604314 https://bugs.launchpad.net/ltsp/+bug/589034 The latter of these references a patch that when applied disables the activation of the nbd-proxy during the client setup process. My success rate for booting clients after applying this patch rises to about %70. Load seems to effect this condition adversely as well as speed and duplex transitions such as many 10/100 clients connecting to a server attached to a gigabit port. The clients in question are Atom based and include gigabit ethernet ports but are connected to 10/100 ports in the classroom. Switches being used include HP Pro-curve edge products as well as a variety of unmanaged 10/100 5-8 port switches. -- Kernel deadlock when running programs from aufs over squashfs https://bugs.launchpad.net/bugs/604314 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
