  Thinkpad T430u won't boot without noapic workaround

Status in linux package in Ubuntu:

Bug description:
  I've used Ubuntu on this specific machine for years without problems,
  but starting with the 4.13 kernel that came with the 17.10 HWE and
  continuing into 18.04 kernels my computer would no longer boot,
  hanging at various screens:

  - A blank screen with a flashing cursor
  - A screen with this message:
  Loading Linux ...
  Loading initial ramdisk ...
  - A screen with kernel messages, ending in:
  APCI: EC: interrupt blocked

  I've encountered the bug in a number of kernels, including:
  - 4.13.0-32
  - 4.13.0-36
  - 4.13.0-37
  - 4.15.0-24
  - 4.15.0-34
  - 4.15.0-36
  - 4.15.0-38
  - 4.15.0-42
  - 4.20.0-rc7

  I was able to work around the issue by adding noapic to
  GRUB_CMDLINE_LINUX_DEFAULT in /etc/default grub, e.g.:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noapic"

  I'm not entirely sure of the consequences of this workaround, but one
  thing I've noticed is significantly reduced battery life.

  This bug seems very similar to what's described here for the Thinkpad

  I'll attach screenshots of various times I've encountered this bug
  over the last year.
