More sleeping woes

More sleeping woes

[Geoffrey Hausheer]

I've been playing around more with acpi, and stil have no luck getting sleep 
to work on my laptop (using either the .24 or 2.5 kernels)

I've pulled the latest 2.4 from linux-2.4-acpi bitkeeper.
I enabled acpi without modules.

I decompiled my dsdt, fixed one of these:
Error 1051 - Access width of Field Unit extends beyond region limit

and one of these:
Warning 2026 - Reserved method must return a value

added the required patches to build in my own dsdt table, and rebuilt the 
kernel.

Now when I do:
echo -n "1" > /proc/acpi/sleep
I just get:
hwsleep-0239 [02] Acpi_enter_sleep_state: Entering S1

and the system freezes solid (I get the same result if I don't use my own 
dsdt)

Besides this, acpi seems to work fine.  All button presses generate correct 
events, and the battery and ac adapter are correctly identified/

I've included the relevant portions of my syslog below.

I then tried using the 2.5 kernel (linux-2.5-acpi), which turned into a major 
pain, since the drivers for my laptop don't compile.

Anyhow, I got it running, but I don't see /proc/acpi/sleep even though my 
syslog shows
ACPI: System [ACPI] (supports S0 S1 S4 S5)

and /proc/acpi/info shows:
states: S0 S1 S4 S5

By the way, the laptop is a twinhead n2380 which uses the sis630st chipset,
and has a PIII (tualatin) mobile processor.

Any other suggestions would be appreciated,
Thanks.
