4.15.0-12.13-generic, from bionic-proposed, fixes this bug for me due to it containing this upstream commit:
1751342095f0d2b36fa8114d8e12c5688c455ac4 Relevant CPU model info from /proc/cpuinfo: cpu family : 6 model : 78 model name : Intel(R) Core(TM) m5-6Y54 CPU @ 1.10GHz stepping : 3 microcode : 0xc2 Model 78 corresponds to 0x4E in hex, which matches this in-kernel model: #define INTEL_FAM6_SKYLAKE_MOBILE 0x4E That's one of the models that was removed in the commit mentioned above. I can also confirm that the flags field of cpuinfo contains "ibpb ibrs stibp". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1755624 Title: With intel-microcode 3.20180312, kernel reports as broken spectre v2 microcode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1755624/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
