[Bug 1055006] Re: Ubuntu 12.10 beta 1 amd64 installer hanging during boot.

[Ankit Saini]

I tried switching to another tty by pressing CTRL + Alt + F1, but I
couldn't since I hadn't completely booted yet. And therefore I couldn't
access the logs.

I actually tried something different. Instead of booting from a USB drive, I copied the contents of the quantal-iso to a separate 
partition on my hard disk and booted from it. This time the system still hanged, but went a few more steps before hanging. 
Earlier it was hanging near the 'Stopped save kernel messages' line, now it hangs after starting LightDM manager.

    Started LightDM display manager            [Ok]


There are also some other confusing things that I cannot understand. Whenever we boot Ubuntu, it by default displays the splash screen. When I was booting from the USB drive I manually edited the /syslinux/txt.cfg file to enable console logging of boot messages. But when I started booting from the partition of my hard drive, there is no splash screen and Ubuntu displays text output by default. I have no idea why is it doing that.

But again, my real problem is that the Installer is not completing the
boot up process. I have tested running the iso in qemu, it booted
successfully there, so it can be made sure that the problem is not with
the my copy of the iso, but rather the installer is having trouble with
my system.

Title:
  Ubuntu 12.10 beta 1 amd64 installer hanging during boot.

Status in “ubiquity” package in Ubuntu:
  New

Bug description:
  About 10-20 seconds after the ubuntu logo show up, the installer simply hangs and nothing happens.
  I edited the syslinux/txt.cfg file to enable console output and I found out that the install hangs at this line :

  "Stopping save kernel messages"

  Is there any way to boot normally now.
