** Description changed:

  Test Case
  1. Boot artful desktop 20170817 under qemu with qxl
  2. Wait until ubiquity-dm is displayed
  
  Expected result
  It boots
  
  Actual result
  It hangs on the splash screen and the dots below the Ubuntu logo are not 
blinking. If the option 'splash' is removed from the boot command line it boots 
successfully.
  
  It also boots successfully with -vga std but in this case the splash
  screen is in text mode not graphical unlike with the qxl driver.
+ 
+ - It started with kernel 4.12.
+ - It is still happening with kernel 4.13.
+ - It only happens when booting from an ISO and not on an installed system.
+ - It works with cirrus/vga, but not qxl
+ - It works if nosplash is set (or splash removed from the boot command line)
+ - It works on Xenial but not on Artful
