Hello ! I've been having this bug as well, when trying to install Ubuntu 17.10 (or fedora 27) in dual boot, and any linux distrib on Virtual Machine (Virtual Box).
The problem is that I can't even boot under Linux (because I can't install it, and I face this problem even with a live-session), so I can't try the commands previously advised. Also, I'm kind of new to the Linux world, so I have no idea on how to "insert intel-ucode.img (taken from recent arch linux iso) as first initrd into grub.cfg". Any clue ? Thanks all for your help, Gaël -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724650 Title: [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please update microcode to version: 0x25 (or later) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1724650/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
