For me, on my laptop (Intel(R) Core(TM) i5-4330M CPU @ 2.80GHz) with Kubuntu 17.10, the 4.13.0-38-generic kernel (signed image) has the same problem. In fact it was slightly worse, a it seems to have wiped out my Ubuntu UEFI booting (boots straight to Windows - I can get to the Ubuntu menu from there and that works). Now fixing that...
Reverting to the older intel-microcode with 4.13.0-38-generic is OK. -- 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
