[Bug 881131] Re: Ubuntu 11.10 freezes during installation on Athlon XP

Sun Oct 30 21:21:25 UTC 2011

Verified, that memtest reports no errors. Ok. (System worked fine all
the time, but who knows ...)

Installed a few times more, always freezes while working on apparmor.

The last line of the syslog is: "in-target: Setting up apparmor
(2.7.0~beta1+bzr1774-1ubuntu2) ..."

The console output after that is:

** Summary changed:

** Package changed: apparmor (Ubuntu) => busybox (Ubuntu)

** Description changed:

  Oneiric freezes during installation (The Release notes did not say, that
  my Athlon XP CPU was too old for Oneiric.)

  a) From Live CD: "Install Ubuntu icon" opens a new window, where I can choose the language. But it won't let me continue, only quit. No matter, which language I choose.
-    When I try to start the installer again, the GUI disappears, the text console appears, with the mouse cursor on top. Cannot switch terminals with Ctrl-Alt-F1/2/3. Only Alt-SysReq-E/U/K/B possible.

+ Everything works fine ... install basic system, enter username, configuring apt, no automatic update, configuring language-pack-en-base, tasksel additional software (none chosen) ...
  up to the point "Configuring apparmor". Then system freezes and the Shift-Lock and Scroll-Lock LEDs on the keyboard begin to flash. No Ctrl-AltF1/2/..., no Alt-SysReq-E/B/... So, unfortunately I cannot tell you anything about the logs.

  From a previous try with the Alternate CD, where I had the syslog
  console active during installation, I remember, that the final message
  was "panic. init terminated." and a BusyBox problem. I do not remember
  the exact call stack output. But if it helps, I can try to re-produce
  it. Maybe I can capture the log output via ttyS0.

- I am not sure, if the problem has really something to do with
- 'apparmor'. I believe, that I have seen the system freeze while
- installing other packages as well (tried alternate install several
- times).
- 
  Probably this is not relevant for the problem, just to let you know: I
  ran both installs via netboot.
