Had a similar problem. WHen I disabled acpi debug messages, i could boot without problems.

Similar problem on a Germicom M6-T. With debug messages enabled the kernel 
will not boot, without _any_ message. With debugging disabled everything 
works fine.

This is the hardest discussion list on which to have a discussion I know!

Can you run with a serial console talking to (maybe) minicom?

That would allow you to get a complete completley accurate log.

Yupp;-)

The following output is only the first part, with 38400 bps on the serial
console the kernel is still booting after 15min. No oops yet, the log
reaches 4MB...  after about 20 minutes ...

(rebooting...)

With this patch the kernel will boot with debug messages enabled.

Oops. That shouldn't have slipped in. Thanks, Ernst. I will upload an
updated 2.4 patch to sourceforge right away.

Jan,

We have discovered a possible situation where an Acquire() with an infinite
wait (0xFFFF) could in fact timeout without obtaining the mutex.  This may
be the root of the problem you are seeing.

Andy is preparing a patch.

To follow up, I get the following at bootup if the fan runs when the box
is booted:

[...]
    ACPI-0226: *** Error: Cannot release Mutex [MEC0], not acquired
    ACPI-1154: *** Error: Method execution failed, AE_AML_MUTEX_NOT_ACQUIRED

ACPI: Fan [FAN3] (off)
ACPI: Processor [CPU0] (supports C1 C2 C3, 8 throttling states)
ACPI: Thermal Zone [THRM] (55 C)
[...]

Maybe this will help.

Hi everyone
Andy, will this patch resolve the problem reported, in boot with debug
messages enabled ?

you will replace patch or you will add this small patch in one extra
file ?
I vote in second choice, because otherwise no one know if have the
correct version or not, and every email reporting problems on boot , we
will have to ask if have this patch applied 


thanks

There's some more fixes made lately, so how about another release in a few
days?

BTW if any of you *really* want to follow ACPI development, let me just
mention again that I do maintain a bk tree at linux-acpi.bkbits.net, and
that is updated with fixes as they are applied.

BTW2 the flood of debug messages should *not* crash the system, so if it is,
that's the real bug to fix.

Hm. If i use a serial console to track the messages, the kernel is 101% busy 
to send it. This seems to be also true, if the console uses a fb-device (you 
don't ever see one message).

Wouldn't that be better at the sourceforge website??

A great problem I found there is the lack of information.

SF doesn't support BK, and CVS is ill-suited for kernel development.

Although more information on the SF site would of course be good.

Maybe thermal throttling is going on? Or machine overheats and bios
slows down to save it.

Worst form of spam? Adding advertisment signatures ala sourceforge.net.
What goes next? Inserting advertisment *into* email?

good for me, I will wait for next release.
Sorry I don't mean bug you.
I have many things to learn and don't have time for bk bits sorry.
Is not in my plans have my own tree :)
if I have an easy way to get patches that are done in your tree, I can
test it more quickly. 

what I thought is: if it is one critical correction, should be mention
in sourceforge.net/projects/acpi. 
by a quick reading of this mailing list, apparently the last patch works
better if we disable debug messages, and this little patch correct the
(critical?) problem. If it not critical correction you are totally
right!

I will be here to test, reporting and try to help get ACPI working in
all computers.
and put this in kernel 2.4 tree.
