amd64-microcode (2.20141028.1) unstable; urgency=medium This release drops support for automatically applying microcode updates without a reboot. The microcode updates can still be applied without a reboot through manual action of the system administrator. This is a defensive measure. At this time, there are no reported issues caused by the AMD microcode update itself when done outside of the boot process. However, updating only on boot works around a very elusive issue in the Linux kernel microcode update driver for AMD processors, which may or may not have been fixed in the latest stable/long-term kernels. It is now possible to configure how the amd64-microcode package should behave through the /etc/default/amd64-microcode file. By default, it will install microcode update support to the initramfs only when running in a system with an AMD processor. -- Henrique de Moraes Holschuh Wed, 17 Dec 2014 19:17:30 -0200
