3. (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.
