Setting debug=all doesn't provide anything useful.   When it freezes, it
still freezes before there's any output.  When it doesn't freeze, I get
all the expected debugging output to the console.

About the only other bit of information I can provide is that when it
does freeze, the keyboard stays backlit.  When it doesn't freeze, the
keyboard backlight goes out.

  No login screen unless "quiet splash" removed from boot line

Status in “grub2” package in Ubuntu:

Bug description:
  I'm not entirely sure this is a Plymouth bug, but here is what's going

  MacBook Pro 1,1 running latest Quantal.

  This machine was running 12.04 just fine, then I upgraded it to 12.10.
  Now, whenever I boot it, I just end up with a black screen, no login
  screen, no apparent cursor, no response to keyboard.

  If, at the grub screen, I edit the boot line and remove "quiet
  splash", the machine boots to its login screen, although it sometimes
  takes quite a long time.  I don't see much on the console output that
  indicates what's going on though.
