[Bug 1167189] Re: boot failure with linux-image-3.2.0-40-generic

Same for me on a Samsung R60 notebook.

I changed the title (hope it's okay) because it has nothing to do with
neither "quiet splash" in grub nor full encryption.

My boot parameters are empty, except removing plymouth it is a quite
normal install.

Removed plymouth on more than five systems on which 3.2.0-40 works well,
so it is not the point.

The boot failure is not happening with 3.2.0-39! Setting "nomodeset"
fixes the problem, but it is a no-go that a security upgrade on the
kernel breaks the system.

If I kill the system and boot again grub pops up and asks for a kernel
to load as always when you hardreset a system. If you choose 3.2.0-40 it
boots! Then I shutdown and boot again...again black screen. And so on.

Title:
  boot failure with linux-image-3.2.0-40-generic

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  From this morning the boot process on my laptop is no longer working.
  The only relevant change from yesterday (when all was working fine)
  has been a kernel update (from 3.2.0-39-generic to 3.2.0-40-generic).

  When grub tries to boot the 3.2.0-40-generic kernel, I get only a
  black screen (the screen seems really powered off).

  After many tries and googling around, I found the following: if I
  change the CMDLINE_LINUX_DEFAULT grub parameter (inside
  /etc/default/grub) from the default value "quiet splash" to
  "nomodeset" the boot process works but the screen has a lower
  resolution than before (from 1600x900 to 800x600).

  This is not happening with the previous kernel version
  (3.2.0-39-generic). Even with "quiet splash" enabled, all is working
  fine with the correct resolution.

  An important note: my disk is fully encrypted (actually the setup is
  LVM + encryption). So when the boot works fine, after the grub
  selection screen I am asked to insert the passphrase for decrypting
  the whole file system.
