Hi, After more than a week of testing, I'm happy to announce that I've solved this issue.
It was a matter of unstable clock, as many others have experienced. The fix was easy, simply add two options to the kernel boot line: "clocksource=hpet" and "notsc". It is enough to edit /etc/default/grub and add the options to the GRUB_CMDLINE_LINUX variable, followed by an update-grub command. -- Randomly fails to start - blinking cursor after grub menu - Compaq 610 https://bugs.launchpad.net/bugs/499220 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
