First of all let me apologize for posting this problem once more. The original
place is https://bugs.launchpad.net/ubuntu/+source/busybox/+bug/881131 (Did not
know, that Busybox has a different place to report problems.)

Ubuntu 11.10 Oneiric Ocelot freezes during installation on
CPU: Athlon XP (0.13)
Chipset: VIA KT400(A)/600.
while working on the apparmor package. This is repeatable. 

I verified, that memtest reports no errors. Ok. 

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

The console output after that is:
