On my second machine, the UUID in /etc/initramfs-tools/conf.d/resume did not correspond to the UUID of my swap partition, so I replaced it by the present one and (after sudo update-initramfs -u) the problem is solved. I don't know why they did not correspond.
On my first machine, I remember having reformatted the swap partition several times to try to solve a problem and finally deleted it and added some RAM. It is probably the reason why the UUIDs did not correspond. Finally we can say my problem and VPablo's problem was not linked with the message "Switched to clocksource tsc". And in fact, I had noticed that most of the time the delay was occurring after that message but not all of the time. So it seems to be just a coincidence, and in our case it is link with a problem of swap UUID. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1308264 Title: Ubuntu boot stuck for more than 30 seconds at "Switched to clocksource tsc" when booting up, then resumes to the login screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1308264/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
