Bug Description

Oneiric freezes during installation.

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.

b) When I try to install from the Alternate CD:
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/...

Probably this is not relevant for the problem, just to let you know: I ran both installs via netboot.

CPU: Athlon XP (0.13)
Chipset: VIA KT400(A)/600

In all cases it was a fresh install of Ubuntu 11.10.

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:
