@Adam/@Serge: could you try the following to see if it solves / reduces the occurrence of the problem. Also, can you report back if you see any "interesting" processes as logged by the change below:
1) Change initramfs to bind mount /dev and dump devices and running processes before udevd exits: $ sudo sed -i.bak -e '/^udevadm control --exit/i echo "XXX: ps=`ps -ef`, \/dev=`ls -l \/dev`" > /dev/kmsg' -e 's!^mount -n -o move /dev!mount -n -o bind /dev!g' /usr/share/initramfs-tools/scripts/init-bottom/udev $ sudo mkinitramfs -o /boot/initramfs.foo 2) Reboot setting "initrd /boot/initramfs.foo" in grub. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/818177 Title: boot failures caused by udev race To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/818177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
