Hi,

I've experimented a little bit more with ACPI and found out the
following things :
With kernel 2.4.21-pre4 when I tried to echo "5" to /proc/acpi/sleep
the console would be killed an the following Oops appeared in the logs :

Attached with this mail is my dmesg (taken from kernel 2.4.21-pre4).

Under kernel 2.5.59-bk2 :
First I set the /proc/acpi/debuglevel to 0xffffffff and when I tried
to echo "5" to /proc/acpi/sleep the system would hang.
The last thing that appeared in the logs is this :
Feb 11 16:07:35 localhost kernel: **** Context Switch from TID 351A to
TID 351C ****
Feb 11 16:07:35 localhost kernel:
Feb 11 16:07:35 localhost kernel:    sleep-0315 [351C] [16]
acpi_system_sleep_seq_: ----Entry

I tried getting swsusp to work (I've applied the s4bios patch).
This works under 2.4.21-pre4 (however, if I start up the X server
after resuming the keyboard and mouse fail to respond).
Under 2.5.59-bk2 I get the error that /proc/sys/kernel/swsusp could
not be found (and yes, I've enabled the software suspend option during
make xconfig).
Is this known or am I doing something wrong here ?

I'm also trying to debug the /drivers/acpi/sleep.c from the kernel
source and hoping to find out what goes wrong.
If I find out more info about this behaviour I will report it to this
list.

Greetings,

Erik van Pienbroek
