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

[mavosaure]

I experiment a similar bug, but I can't be sure it's exactly the same. I
hope we'll find something to explain and resolve our problems.

After testing without any problem the Kubuntu 12.10 beta 2 (amd64
flavor, install with live-usb on a test partition), I try many times
after the release to set up Ubuntu 12.10 (in replacement of my "old"
11.10).

Everything I try fails (all with live-usb) :
 - Ubuntu 12.10 64
 - Xubuntu 12.10 64

on messages as "stopping save kernel messages    OK"
or "starting CUPS printing spooler/server   OK"

I tried boot options as acpi=off, noapic, nolapic without any
amelioration.

Finally, I try Ubuntu 12.10 64 server with a minimal config... and it works. 
But after reboot, when I did a sudo apt-get install ubuntu-desktop, I got many times the message

"FATAL: could not load /lib/modules/3.0.0-12-generic/modules.dep: No such file ord directory"
Amazing if we consider that Quantal uses linux 3.6....
After this error, when I rebooted, my install was dead (again).

Finally I tried again Ubuntu 11.10 64 which got installed without any problem. And now 12.04.1.
But I'd like to understand why I'm damned with 12.10. And if I have to prevent my system to upgrade to 12.10

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

Status in “ubiquity” package in Ubuntu:
  Confirmed

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.
