Description Aurele Theriault 2012-04-19 03:41:47 UTC

Overview: Acer NetBook AO722 freezes shortly after booting (from Power ON), no hardwired network connection but WiFi active; first boot device is HDD0. BUT after making changes in BIOS boot sequence, boots ok (without power off / power on) and does NOT freeze. Same problem confirmed with Kernel 3.2.0-23-generic
See Bug report: https://bugs.launchpad.net/bugs/983514

Workaround: change BIOS boot sequence to have 'Network Boot' as FIRST boot device, before HDD0. Network Boot times out then HDD0 boots ok and no freezing thereafter.

Steps to Reproduce:
a-power on; F2; configure 'Network Boot' as first boot device in BIOS and 'HDD0' as second; F10
b-without power off, reboot; network times out then HDD0 boots ok and no freezing;
c-power off then power on; network times out then HDD0 boots ok and no freezing;
d-power off then power on; F2; configure 'HDD0' as first boot device in BIOS;F10;
e-do NOT power off; just reboot; no freezing;
f-repeat step 'e' several times; no freezing;
g-power off then power on; boots from HDD0 and freezes.

Note: This problem was there in Ubuntu 12.04 since the first alpha I tested.

Here is a simpler way to reproduce this problem

Prerequisites:
1-on battery power; no AC Adapter
2-no wired network connection
3-active WiFi connection
4-power on
5-set BIOS boot sequence: 1 . HDD0
6-power off

Test #1: freezes; dmesg output attached file 'dmesg-FREEZE'
1-power on
2-F12 select HDD0
3-boot
4-freezes
5-power off

Test #2: OK no freezing; dmesg output attached file 'dmesg-OK'
1-power on
2-F12 select Network
3-boots
4-keeps working
5-shutdown

Hi Aurele, 

Please help to check does this issue causes by acer-wmi, please add acer-wmi driver to blacklist in /etc/modprobe.d and try to reproduce issue.

thanks

Performed test listed on 2012-04-19 19:09:03

COLD BOOT with:
Linux AOU1204 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Result: identical.

performed system update then
COLD BOOT with:
Linux AOU1204 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
Result: identical.

added blacklist acer-wmi

COLD BOOT again;
Result: identical.

It appears that this problem is not caused by acer-wmi.

I asked because the system message stop on before acer_wmi load.

Per success dmesg on comment#10:
...
[    7.446975] psmouse serio1: synaptics: Touchpad model: 1, fw: 7.2, id: 0x1c0b1, caps: 0xd04733/0xa40000/0xa0000            <=== freeze here
[    7.500828] acer_wmi: Acer Laptop ACPI-WMI Extras
[    7.500875] acer_wmi: Function bitmap for Communication Button: 0x1
[    7.500889] acer_wmi: Brightness must be controlled by acpi video driver
[    7.529154] input: Acer WMI hotkeys as /devices/virtual/input/input8
[    7.584031] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input9

Have the following questions:
 + Does this issue also happen on runlevel 3 ? When system doesn't launch X-window?
 + Per dmesg log, does it always freeze before acer_wmi load? or it's random freeze on any driver message in dmesg?


Thanks
