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: [ 574.367268] busybox[1]: segfault at 95f7504 ip 08073fc9 sp bf9ec98c error 4 in busybox[8048000+4a000] [ 574.478310] Kernel panic - not syncing: Attempted to kill init! │ [ 574.549267] Pid: 1, comm: busybox Not tainted 3.0.0-12-generic #20-Ubuntu┘ [ 574.630520] Call Trace: [ 574.659831] [<c1518c98>] ? printk+0x2d/0x2f [ 574.710876] [<c1518b76>] panic+0x5c/0x151 [ 574.759850] [<c104b244>] forget_original_parent+0x1e4/0x1f0 [ 574.827553] [<c152c6fd>] ? _raw_spin_lock_irqsave+0x2d/0x40 [ 574.895233] [<c104b263>] exit_notify+0x13/0x140 [ 574.950452] [<c104ba6d>] do_exit+0x1ad/0x3a0 [ 575.002545] [<c104bdb8>] do_group_exit+0x38/0xa0 [ 575.058807] [<c105a6b5>] get_signal_to_deliver+0x215/0x3c0 [ 575.125497] [<c10e5324>] ? free_pages+0x34/0x40 [ 575.180773] [<c152fa00>] ? vmalloc_fault+0xee/0xee [ 575.239104] [<c1002801>] do_signal+0x61/0x110 [ 575.292244] [<c152a4d1>] ? schedule+0x2f1/0x680 [ 575.347458] [<c152fe9b>] ? do_page_fault+0x49b/0x4a0 [ 575.407868] [<c1049ad0>] ? wait_task_continued+0x140/0x140 [ 575.474522] [<c1002ad5>] do_notify_resume+0x75/0x90 [ 575.533898] [<c152c9b0>] work_notifysig+0x13/0x1b ** Summary changed: - Ubuntu 11.10 freezes during installation on Athlon XP + Ubuntu 11.10 freezes during installation on Athlon XP. Segfault in BusyBox. ** 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. + 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) ... + 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.
