Did this work with any kernels before 2.6.17? 
Does it work with 2.6.18? 
Comment 7 Markus Feldmann 2006-09-20 00:07:41 UTC
In debian the newest linux-source is 2.6.17-9
but i will try it at weekend. I will report it.

kernel-image-2.4.27 did work well, but i think this was compiled with apm.
I am not sure.

I didnt test apm.
Another thing is that it only sometimes goes wrong.

Ok I installed the 2.6.18 from www.kernel.org .

The most time it worked for me, but sometimes it hangs up too.

How can I get debug messages which i can post ?
Comment 9 Markus Feldmann 2006-09-21 07:17:09 UTC
I activated the debug in the Kernel/ACPI.
How can I get more debug messages?

Here comes the message on shutdown,
...
Done unmounting localfilesystems.
Mounting root filesystems read-only ... done.
Will now halt.
Synchronising SCSI cache for disk sda:
Powerdown.
acpi_power_off_called
hwsleeg-0285[02] enter_sleep_state: Entering sleep state [S5]



Why does my disk syncs after he gets read-only?
Could it be that he get trouble with the syncing time?
Comment 10 Len Brown 2006-09-21 10:36:23 UTC
Please re-open this bug when the failure reproduces w/o   
loading the binary nvidia module.

This means that Linux is getting to the right place to power-off. 
However something has confused the firmware such that the request 
fails.  Try simplifying the system by removing as many device 
drivers as possible -- it may be possible to isolate the failure 
to a particular device driver. 
 
Re: older releases.  2.4 is too old to be interesting, but if you could 
try something from kernel.org older than 2.6.17, it would be helpful 
to know if this system never powered off with 2.6, or if this has 
recently broken. 
 
Re: dmesg, be sure to use dmesg -s64000 to capture the full buffer 
back to the beginning.
