** Attachment added: "intel.txt" https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1746200/+attachment/5045553/+files/intel.txt ** Description changed: The version "3.20180108.0+really20170707ubuntu17.10.1" of the package "intel-microcode" randomly freezes Ubuntu at boot (at a very early stage, nothing is written on the screen). The number of hard reset of the computer required looks random but it works at third boot most of the time. I was previously affected by the 20180808 regression : https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1742933 Symptoms are the same. user@PC:~$ dmesg | grep microcode [ 0.000000] microcode: microcode updated early to revision 0xba, date = 2017-04-09 [ 0.986254] microcode: sig=0x506e3, pf=0x20, revision=0xba [ 0.986730] microcode: Microcode Update Driver: v2.2. If I uninstall "intel-microcode" everything is fine. user@PC:~$ lsb_release -rd Description: Ubuntu 17.10 Release: 17.10 This install is relatively fresh as I did it when I was affected by the 20180808 regression. Xubuntu 17.10 installed on a SSD with LUKS encryption user@PC:~$ uname -a Linux PC 4.13.0-32-generic #35-Ubuntu SMP Thu Jan 25 09:13:46 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux Package Manager = synaptic 0.84.2 Computer : Model = Asus N752VX-GC164T Bios = v301 (13 oct 2016) - Processor = Intel Core i7-6700HQ (6e gen Skylake) + Processor = Intel Core i7-6700HQ (6th gen Skylake) Nvidia graphic card = Grub is configured with "nouveau.modeset=0" Sorry I can't give more accurate description of the bug. I don't see any error message on the screen at boot. Is there somewhere a boot log I can provide ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1746200 Title: Regression in 2017-07-07 updates To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1746200/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
