@debfx this is precisely why intel microcode package should be consistently installed and this is done in response to the TSX problem described before. microcode update is the last resort that vendor has to correct firmware bugs in the field. microcode update removed TSX instruction because the implementation turned out to have issues. But that was not sufficient alone, due to incorrect detection in the user- space code and the fact that microcode is not updated on most client systems. This one of the corrective actions going forward to mitigate / contain similar type of problem in the future.

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.
