Title:
  Lenovo T420s boot problem

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Having enabled the nvidia graphics card on a Lenvo T420s (4174) it's
  locksup around the time udev get's executed on boot.

  01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [NVS 4200M] (rev a1)
  01:00.1 Audio device: NVIDIA Corporation GF119 HDMI Audio Controller (rev a1)

  Problem can be avoided by adding "nox2apic" to grub boot line.
  But this should not be needed!
