At that moment in time, the microcode *is not changed*. Only a *reboot* (or shutdown + powerup) would load the new microcode update. That means the update run hang with whatever older microcode and kernel you already had at the time -- so, it was not caused by the intel-microcode update, *unless* you already had intel-microcode installed and had already rebooted for some reason. > Downgrading intel-microcode to 3.20191115.1ubuntu3 and regenerating the > initramfs fixes the problem. If it is not asking too much, with the computer fully stable and intel-microcode 3.20191115.1ubuntu3 installed (*and* rebooted so that it got applied to the processor), could you please do another install cycle, *just* with the intel-microcode security update that supposedly caused issues? It must complete the update safely, it will not attempt to update the processor. Only when you reboot, will it attempt to install the updated microcode into the processor. Please ensure you have enough free space in /boot: if it fills up, *bad things can (and likely will) happen* the next time you reboot. If the reboot to activate the microcode update does hang, does it also hang when powering up the computer with the new microcode package installed (instead of rebooting)? -- Henrique Holschuh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1883002 Title: intel-ucode 20200609: hangs on Whiskey Lake To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1883002/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
