@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.

Title:
  4.18.0-14 doesn't boot past grub

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  4.18.0-14 doesn't boot past grub for me in thinkpad t510i. 4.18.0-13
  worked fine. I had to revert back  to 4.15 kernel. I'm using a distro
  that is based off of Ubuntu 18.04.

  System info:
  CPU:    Intel(R) Core(TM) i5 CPU       M 520  @ 2.40GHz
          4 cores/threads
          2400.00 MHz
  RAM:    7.59 GiB

  I'm not sure how to provide crash info, as the kernel doesn't boot.
