Gericom Hummer 2430 problems

Gericom Hummer 2430 problems

[Sebastien B]

Hello,
I have several problems with my Gericom Hummer 2430 laptop :
- I can't change the CPU throttling settings. When I write to 
/proc/acpi/processor/CPU1/throttling, nothing happens and the contents of 
this file remain unchanged. Writing to /proc/acpi/processor/CPU1/limit 
doesn't work either. There isn't any error message displayed in the dmesg 
output nor in the console.
- Sometimes my machine locks up for less than a second and when this happens I 
have the following message in the dmesg output : 
atkbd.c: Unknown key pressed (translated set 2, code 0x0, data 0x0, on 
isa0060/serio0).
I'm unsure this problem is ACPI related, but it often happens when the fan 
starts up.
- The S-states just don't work. Trying to enter one either does nothing or 
crashes the computer. The computer shutdowns properly, though.
I'm using Linux 2.6.0 with the ACPI patch 20031203.
You can find useful information about my laptop (contents of the DSDT, full 
output of dmesg and so on) at http://irchat.free.fr/acpi/.
Thank you,
Seb

Maybe this is ec event handling relative bug.  Please file it
on bugzilla.

What kind of crash? Maybe this could the most easy one. :)

I've recently noticed that this bug only happens while KDE is running. 
It's quite weird... and it is not only because of KDE : it locks up the 
whole system ; if I'm listening to music when the bug happens, there 
are interrupts in the song... I had the same problem with Linux 2.4.23 
but without any message in the dmesg output.

S1 is not recognized (as written in the dmesg), and when entering S3 
the screen is turned off, and the machine is not responsive anymore to 
anything (even to the power button or to the LAN). I haven't tested S4 
and S5.

I have another problem : the contents of the /proc/acpi/ac_adapter/AC0/
state are not updated when I plug or unplug the AC adapter. The 
contents of this file are set correctly at boot time, and then there 
isn't any change until I reboot.

It happens because of the aKpi (battery monitor) applet is loaded on 
login. It's is not because of aKpi itself, I can trigger the same 
problem with the Gnome battery monitor applet. So this is definitely 
ACPI related...

I'd second that.  I'm seeing it with Sun JDS.  Easy reproduce-by: enable
the gnome battery applet, leave system on overnight.  Results in a
locked system the next day.  Disable battery applet, no locked system. 
I'm sure it's a corner-case hiding in the driver - just haven't had the
time to go after it and thought that it might have been quashed in
modern versions of the ACPI support.

How can an battery monitor applet locks up the whole system?

The symptom seems to indicate there are some bugs triggered by 
the battery monitor applet. We need to figure out what is the applet
doing , then we can deeply look into ACPI code.

Possible next step is while true; do cat batery/*/*; done, and see how long
it takes before lockup.
