We have now confirmed that the problem is the NFS mounts in /etc/fstab. Setting the NFS entries in fstab to "noauto" completely removes the problem: There is no timeout during boot, and no lockup any more. The machine boote smoothly with the NFS-shares unmounted. After the machine is up, we can manually mount the NFS-shares without a problem.
This is definitely a race condition during bootup: the NFS shares seem to be mounted at a time, where the network is not yet up, and waiting for the network to come up locks up the boot process. ** Summary changed: - Possible race condition with NFS mounts causes boottime hang + Race condition with network and NFS mounts causes boottime hang -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1118447 Title: Race condition with network and NFS mounts causes boottime hang To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1118447/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
