How long will it take to get this into Trusty?  Or would I have a better
time installing the Wily Beta?

Since 4.2.0 seems to work in SMP mode, my only issue is lack of drivers
for wifi and such. (And trusty in UP mode seems to run very, very hot
and is working the fan to death).

Title:
  Fails to boot on Macbook Air 2013 (Haswell) in SMP mode, needs nosmp
  to boot

Status in linux-lts-utopic package in Ubuntu:
  Confirmed
Status in linux-lts-vivid package in Ubuntu:
  Confirmed

Bug description:
  I keep running into issues with booting on a 2013 Macbook Air.  After
  grub, the kernel and initrd load and the system then just hangs with a
  blinking cursor.

  Removing the "quiet" and "splash" options shows me that the kernel
  hangs bringing up SMP, just as in bug #1197451 which has been marked
  Fix Released already (some time ago, actually).

  I get exactly what was mentioned in the comments about SMP hanging and
  have had to manually inject nosmp into the boot command when I boot
  the machine.
