All Ubuntu kernels with the latest intel-microcode suffer this bug on my HW. I need to do any of these three workarounds to be able to boot: 1/ use non-ubuntu kernel (I have liquorix) 2/ disable microcode updates during boot: dis_ucode_ldr param 3/ downgrade the intel-microcode package to bionic/main version > report the output of 'dmesg | grep microcode' when bboted in this > configuration to make sure that the initramfs is loading the updated > microcode in that case # uname -a Linux mmm-U2442 5.0.0-15-generic #16~18.04.1-Ubuntu SMP Tue May 7 14:17:37 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux # dmesg |grep microcode [ 0.185333] MDS: Vulnerable: Clear CPU buffers attempted, no microcode (^^^ this is with latest intel-microcode package (from 2019) and the dis_ucode_ldr...so apparently the ucode is not loaded) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829620 Title: intel-microcode on ASUS makes kernel stuck during loading initramfs on bionic-updates, bionic-security To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1829620/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
