I confirm this issue on Ubuntu Server 12.04.2 LTS with udev version 175-0ubuntu9.3
Here, apt-get dist-upgrade hangs in udev start of update post-install phase with the same strace as in the description. Reading through the Turnkey Linux forum thread referenced in comment #1, I was able to resolve the deadlock by "service udev stop" in another terminal, while the update still hangs in udev start. This hangs too, but now the update continues and succeeds. Last, I had to terminate the stop command by hitting Ctrl-C -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/674704 Title: "restart udev" hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udev/+bug/674704/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
