> Can someone pls guide me step-by-step how to solve it? This is not an Ubuntu bug. Your processor microcode (firmware) is old and contains bugs. Sometimes motherboard BIOS updates contain processor microcode updates, but not always, and BIOS isn't always at the latest level.
To allow Ubuntu to update your processor microcode, do this (don't type in the $ character): $ sudo apt-add-repository restricted $ sudo apt update $ sudo apt install intel-microcode $ sudo reboot > I got this bug as well. See above; this isn't an Ubuntu bug. Feel free to do the above steps to allow Ubuntu to install updated processor microcode on each boot, to address the buggy microcode in your CPU. > My system is not shutting down as well. That's unrelated to this bug. -- 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
