This are very good numbers, which I've expected.

This should be easily solved.

I point on your distro's startup scripts. They only look if apm is enabled 
but _NOT ACPI...

Have a look into /etc/init.d/halt (taken from SuSE 7.3, LSB standard).

ACPI trouble (Was: Re: [patch] amd athlon cooling on kt266/266a chipset)

Hello Dieter

Yup, just a danish letter in my middle-name :-)

Well, RedHat 7.2 does not look if apm or acpi is configured, it just 
uses -p unless the command run was 'halt' or 'reboot'.

When running '/sbin/poweroff' from single-user, 'halt -i -d p' is the 
last command run by the halt script. The I get the message 'Power down.' 
from the kernel and my system just hangs here.

When running /sbin/poweroff from runlevel 3 or 5, 'halt -i -d -p' is 
again the last command run, follwing this from the kernel:

Power down.
 hwsleep-0178 [02] Acpi_enable_sleep_state: Entering S5

And again my system hangs. Pressing the power button for 4 seconds turns 
off the computer (the BIOS is set to 'immediate power off'). 
Ctrl-Alt-Delete or any other keyboard combinations do not work.

Reboot works fine. APM poweroff also works flawlessly (but then I do not 
get the powersaving functions).

In runlevel 3, the following modules are loaded (some are patched in 
from the iptables package. They should not cause this, as I can 
reproduce this without iptables configured/patched at all):

I have tried different ACPI configurations, but I haven't been able to 
make any of them work.

I have very little knowledge of ACPI, but I'll be happy to help (if this 
is not my fault of course - then I will apologize for taking your time 
:-)).

I have an ASUS A7V motherboard, similar to your ASUS A7V133.  I find
that stock kernel (2.4.18-pre7) APM powers off the machine, but stock
kernel ACPI does not.  However, the Intel ACPI patch, available from
http://developer.intel.com/technology/IAPC/acpi/downloads.htm against
kernel 2.4.16, does power down my machine.  I was able to forward port
this to 2.4.18-pre7 without too much trouble by starting with 2.4.16,
applying the Intel ACPI patch first, and then applying kernel
patch-2.4.17 and kernel patch-2.4.18-pre7.

As to the merits of the amd_disconnect patch that started this thread,
under 2.4.18-pre7-acpi, I get an idle CPU temperature of about 48 C.
With the amd_disconnect patch, it drops to 32-35 C, wow!  As
previously discussed, APM + amd_disconnect on an Athlon does not
provide any power savings, one needs ACPI + amd_disconnect.

Note that on this motherboard (and perhaps all ASUS Via chipset
motherboards, including the A7V133), one needs the following line in
/etc/sensors.conf to get reasonable lm_sensors CPU temperatures:
  compute temp2 @*2, @/2
This is as described at http://www2.lm-sensors.nu/~lm78/support.html
in Ticket 775.

Best wishes,
Wayne

I still have this in my tree. I have no idea who is wrong, whether parser
or BIOS.

I have ASUS A7V266-E (AS99127F chip) and lm_sensors 2.6.2
shows 43 C for CPU without any additional lines in /etc/sensors.conf

Which sounds reasonable.   However this temperature is rarely ever change !
I typically have 43.1,   sometimes 42.8   and that's it.   Even after 2-3 min

compiles.    So something is wrong

Thanks for the tip; now it works. And besides I installed acpid - pretty 
cool to get a clean shutdown when the power-button is pressed :-)

Eek, so my BIOS was right after all :-) The system is 63C at high load 
and 45C with the disconnection patch and ACPI enabled. With normal APM 
and no disconnection it is around 60C.

Thanks anyway.

Re: ACPI trouble (Was: Re: [patch] amd athlon cooling on kt266/266a chipset)

[Kevin P. Fleming]

Actually, I used a separate temperature sensor to come up with proper values
for lm_sensors to read the CPU temperature on my A7V (ver 1.01). After
testing lowest and highest temperatures, this what I came up with:

  compute    temp2     28.2+((@-18)*2), ((@-28.2)/2)+18

I know it looks weird, but it makes the "sensors" value for CPU temperate
match (within .5 degrees C) across the entire range I can test (which is
from full load on a 1GHz Thunderbird down to idle and using the old "lvcool"
patch).

What if you do it by hand?

Maybe this is an indication of broken BIOS.
You should grep for the ACPI diagnosis tools and send your results to the 
acpi-devel list.

Unknown device 8042

Maybe here is something missing, too.

ok .. .maybe someone should look what the differences for the "halt"
functions are ... i risked a short look in the acpi sources, but i have
not the time to compare the patches at the moment ... maybe at the weekend
... but the acpi sources don't look like easy to understand :) (like many
parts of ther kernel ... imha as a kernel newbee :) )

yes ... you  have no working power-saving ... so the cpu runs at full

And another.  Dropped my CPU from ~50+C down to 39C (I have a hot
case).  I haven't had any problems but its a headless, no keyboard/mouse
machine.

Eh, it signals init to go to runlevel 0. Apparently it is some kind of 
wrapper.

Another broken BIOS implementation...

Btw. I'm running with BIOS 1005A. I did not dare to flash to 1007 as the 
flash program is telling me, that the 1007 BIOS is for "A7V133-C" while 
my current BIOS is for "<A7V133>"...

Eh, is that the pmtools package? If so, I have put output from the 
programs at http://www.amagerkollegiet.dk/~moffe/acpi/

If the Linux ACPI implementation takes over control of the button, it 
should be ok or what?

I just tried the same ACPI configuration as you; no change - it still 
hangs at 'Power off.'.

I have put it in the same place 
(http://www.amagerkollegiet.dk/~moffe/acpi/) as acpi-old.txt. Also there 
is the dmesg from the kernel with the acpi-patch (from the intel site) 
applied.

Done (however I'm not a list member myself).

I've put the output from 'lspci -vvv -xx' on the same site 
(http://www.amagerkollegiet.dk/~moffe/acpi/) if it should show up to be 
helpful.

Re: ACPI trouble (Was: Re: [patch] amd athlon cooling on kt266/266a chipset)

[Wayne Whitney]

Nice job, Petr, you rock!  Your patch allows my ASUS A7V BIOS 1009 to
poweroff off under kernel 2.4.18-pre7 with ACPI.  Much easier than the big
ACPI patch against 2.4.16 from Intel.

Cheers, Wayne

Your patch might work on the A7V, but it does not on my A7V133-C. If I 
modify the OEM string in the patch, it works. It may also be modified to 
[...] "A7V-133", 7)[...] but then it probably won't work on a A7V...

As said in another post, the patch from the intel site also solves the 
problem.
