I hit this bug while trying to install a kernel upgrade (going from the default 4.13.0-16-generic to 4.13.8-041308, from the mainline PPA). I managed to get an strace from running "plymouth --ping". In the attached trace file, the hang happened on the last call to epoll_pwait.
I also tried attaching strace to plymouthd, but when I did that, it caused plymouthd to immediately exit (which in turn caused plymouth --ping to return). After that, subsequent runs of "plymouth --ping" returned immediately (getting ECONNREFUSED on the "/org/freedesktop/plymouthd" socket), and I haven't been able to reproduce the bug since. ** Attachment added: "plymouth.strace" https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1705345/+attachment/4975330/+files/plymouth.strace -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1705345 Title: Installing new kernel hangs on plymouth --ping To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1705345/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
