I'm still unable to reproduce these lock ups and I've tested on three different systems. So, I'm reliant on you (very helpful) bug reporters.
Could someone test out the 4.13.0-38-generic kernel from artful-proposed to see if you experience any lock ups with the 3.20180312.0 microcode? In the meantime, I'm looking through the changes between 4.13.0-36 and 4.13.0-37 to see if there's anything that sticks out. Nearly all of the changes are ARM related so that limits the possibilities in a nice way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759920 Title: intel-microcode 3.20180312.0 causes lockup at login screen(w/ linux- image-4.13.0-37-generic) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-microcode/+bug/1759920/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
