#401 closed defect (fixed)

Intel ATOM system routinely hangs at boot logo

Reported by: mobybrick Owned by: eco
Priority: major Milestone: Feedback pending
Component: ACPI PSD Version: 3.16
Keywords: Cc: mobybrick


Guess this might be the same boot hang that lots of people have.

Booting is sucessful in 1 out of 5 boots; most of the time it hangs at eCS boot logo.

ACPI currently at 3.12, will try 3.15 if this is likely to improve things.

Thanks, Moby.

1) What is the model of PC?

2) Let's test ACPI 3.14 (and there is acpi 3.15 in your Mensys directory with special builds --

3) Show us switches which you use with ACPI.PSD, better collect detailed logs -- ACPI Logs Collector 3.14 (

or simple log: copy acpica$ acpi.log and attach it

Version: 3.123.15

Logs collected using ACPI logs collector 20081203.

Latest ACPI 3.15 09_05_09 build.

System will *always* hang when booted from cold power-just-plugged in; works after warm reset (i.e. reset after hang).

Duplicated on an identical system; systems are generic systems with genuine Intel Atom LF2 Mainboards and integrated dual-coe Atom CPUs.

Please let me know if there is anything else you need; I have a bit of time this week for any additional testing you need.

OK, to summarise - system seems to hang very often at random on eCS boot logo at completely random moments. Not sure that cold boot is anything to do with it.

Main problem: hang on OS2LOGO

The user is waiting for support --

Message 1:



OK, ticket 401: you have attached logs..

Please try boot in /SMP /APIC mode

First of all, please test ACPI 3.14. Your computer should work with this version.

Then try ACPI 3.16

Please post to the acpi bug-tracker additional information:

1) post output of:

2) hang on OS2LOGO => -> LOGS-1

Message 2:

Sorry, I don't think you understand. 3.14 does not work. I've been testing ACPI on Intel systems for two years since ACPI-OS2 v2 and it has *never* worked reliably.

For this particular system, I've already attached the logs for version 3.14 to the SVN ticket months ago, with no response. I've also tried several versions of ACPI 3.xx, leading upto and including 3.14 and 3.16.

A run of ACPI-TEST.CMD reveals no problems on the system. It warns of the SNOOP.LST should only have IBMKBD.SNP - which it only does anyway, so ACPI-TEST.CMD seems to be buggy in itself.

I will try to copy the debug ACPI.PSD (I've already remote the OS2LOGO file) but having done this process with several Intel systems previously, are you sure this can be fixed?

Message 3, Message 4

Milestone: Release version 3.15Release version 3.16
Version: 3.153.16

I installed debug version of ACPI 3.16

  • Copy ACPICA$ logfile does not work
  • Hang at boot logo hangs at the following:


When it hangs here, the machine seems to hard hang.

Sometimes the hang occurs after an additional line:


and on this hang the machine will reboot if CTRL-ALT-DEL is pressed.

Many of the hangs with ACPI that I have reported previously have been at 'UNMASK' statements.

Any chance of some help with this?

What is options for acpi.psd ? What do you mean copy acpica$ acpi.log don't work? What is setting in %etc%\AcpiD.cfg in AcpiLog? = ?

comment:7 Changed 11 years ago by mobybrick

  • I have tried no switches, and /APIC = no difference.
  • ACPID.CFG file is default.
  • The command 'Copy acpica$ logfile' produces 'The system cannot open the file or device specified'

Please see the attached logs from the ACPI log collector - I'm guessing that is where all the information is stored.

Thanks for the response Pasha...

Do you try acpi.psd /SMP /!NOD ?

comment:9 Changed 11 years ago by mobybrick

  • Another dump screen attached of a hang
  • 'Copy acpica$ logfile' fails if ACPIDAEMON running, so I've got the output of this before and after shutting down ACPIDAEMON

1st log: 21:43:32 Button KernBlock? 4294967295 timeout

2nd log: 21:48:5 Button event rc 95 21:48:5 Button KernBlock? rc=95

  • Booting with /!NOD seems to work after the few boots I have so far tried; from docs this seems to suggest the another ACPICA.ADD file is required in this mode, but cannot find one. Does /!NOD indicate a problem with the OEMHLP$?


comment:10 Changed 11 years ago by mobybrick

Spoke too soon, system still hangs at boot, this time with a different message. See photo of boot screen below - indicates 'no response' from something.

Seems to hang every other boot, as before.

comment:12 Changed 11 years ago by pasha

Can you install debug kernel and os2ldr from with dbport=0. Then attach photo at hang

comment:13 Changed 11 years ago by mobybrick


Is using debug kernel and loader from ACPI316FULL package OK?

Wasn't aware that there are any debug kernels on Hobbes :)

Yes, you can use from debug directory and add this .sym

comment:16 Changed 11 years ago by pasha

Ok. Do you change kbd driver? Do you use KVM? What is your keyboard? PS/2 or USB?

comment:17 Changed 11 years ago by mobybrick

  • No changes to keyboard driver.
  • Usually the system has no keyboard (or mouse) attached when in use, as I control it via VNC
  • For testing the results above, it has PS/2 keyboard and mouse.
  • Adding the keyboard and mouse has not changed the frequency with which it hangs

comment:18 Changed 11 years ago by mobybrick

Is there anything else I can try?

I have an identical system to this that behaves exactly the same.

comment:19 Changed 11 years ago by mobybrick

If I boot with the debug version of ACPI.PSD, but without /01 and boot with not the debug version of OS2KNRL, but the usual build, I get some very interesting info when the hang occurs:

Wait INI App Proc Send SIPI1 Send SIPI2 Start Processor unsuccess

Is this of any help? Is there any chance this will be fixed?


comment:20 Changed 11 years ago by mobybrick

... but I also still see it hang much latter at the mask statements, so I suspect that there are not one but TWO problems with the ACPI code that prevent booting.
