(Optional) Hold the package so that it won't be upgraded accidentally sudo apt-mark hold intel-microcode [Impact] * Some systems experience kernel lockups after updating to the latest intel-microcode package or when receiving updated microcode from a BIOS update. * In many cases, the lockups occur before users can reach the login screen which makes it very difficult to debug/workaround. [Test Case] * The most reliable test case currently known is to install the sssd package. Lockups may occur during package installation (disable IBPB by writing 0 to /proc/sys/kernel/ibpb_enabled to prevent this from happening). A lockup will most likely occur just after booting the system up as the lock screen is displayed. [Regression Potential] * The fix is in the task switching code of the kernel so complexity of the change is relatively high. [Original Report] I don't know if this is a problem with the kernel or the microcode, but we have a significant number of computers in our organization (on both 16.04 and 17.10) that fail if they have both updated.
