You will want the newer intel-microcode packages, then. This means a resync with Debian is highly advised.
Exactly due to the issue brought to the front by the Intel Haswell microcode update that disabled TSX, Debian has switched to enforcing that automated microcode updates be done only through the early initramfs. This, in fact, requires a reboot to apply the microcode update (just like a kernel update). While I did blacklist the offending Haswell microcode updates in the Debian packages so that they will not be applied by accident using the late microcode driver (which results in an unusable system as described in #1370352), this kind of blacklisting is reactive, so the switch to early microcode updates is the only safe way forward right now. Of course, it took ~10 years for the first Intel microcode update that had visible effects at the ISA level to show up, so it might be another 10 years before the next one... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/1386257 Title: intel-microcode should be installed by default, when the CPU is GenuineIntel Status in intel: New Status in ubuntu-drivers-common package in Ubuntu: In Progress Status in ubuntu-meta package in Ubuntu: In Progress Bug description: intel-microcode should be installed by default on the bare-metal systems which are running on GenuineIntel CPUs, by the installers. Similarly other microcode packages for other CPUs brands should be considered for inclusion (e.g. amd64-microcode). I hope that ubuntu-drivers-common can gain ability to detect cpu series and/or vendors, packages that provide microcodes similarly declare support for cpu series and/or vendors, the microcode packages are shipped on the CDs in the pool directory, and installed on to the target machines as part of the installation. This should help with rapid correction of bugs and behaviour of the CPUs in the field.
