@Jan Schnackenberg: Thanks for that feedback and helpful and analysis. The Spectre-related change looked suspicious at first. However, if that was indeed the cause of your issue, then it's almost certainly a different issue than the one described in this bug report and experienced by @P.D., since at this point in the bisection, we've eliminated Spectre-related changes from the pool of possible culprits.
In fact, at this point it's highly likely that the problem is a regression in the Intel i915 driver. This matches with the stacktraces in all the bug reports so far, and also coincides with a few i915 changes on which we're narrowing in in the bisection process. @Jan Schnackenberg, you are encouraged to try the test kernels that I've linked above and report your results. Your problem is almost certainly the same problem described in this bug (and if it's not, we can continue that investigation as part of another bug). As for the required .deb files, you can forgo the -headers files, so the following should be sufficient: linux-image-unsigned-4.18.0-14-generic linux-modules-4.18.0-14-generic linux-modules-extra-4.18.0-14-generic Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813657 Title: 4.18.0-14 doesn't boot past grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1813657/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
