I have prepared test amd64-microcode packages in the ubuntu-security- proposed ppa https://launchpad.net/~ubuntu-security- proposed/+archive/ubuntu/ppa/ ; it would be great if someone could test one of them on a system with an AMD 17h family processer before they get uploaded to the various proposed pockets.
(Please note that the Ubuntu Security Proposed PPA should not be generally enabled, as it receives packages that have not been tested yet.) Thanks! ** Description changed: [Impact] * New microcode is available for AMD family 17h processors as of 2019-10-22. [Test Case] * There is no testcase for new microcode, as it is unknown what has changed. [Regression Potential] * New microcode is published without a changelog, thus it is unknown what it fixes or regresses, yet it is recommeded to upgrade it. The 17h family microcode has been updated [Other Info] * https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/commit/?id=2b016afc348ba4b5fb2016ffcb2822f4a293da0c + For all proposed packages, the change to not override preset defaults + from auto-exported conf snippets loaded by initramfs-tools + (http://launchpadlibrarian.net/435434785/amd64-microcode_3.20181128.1ubuntu1_3.20181128.1ubuntu2.diff.gz) + is incorporated in addition to the newer microcode.
