Centrino acpi issues

Hi everybody

I have some problems running kernel 2.6.4 acpi on my centrino notebook.

1. When i issue a shutdown command I only get a message saying:
'acpi_power_off called'. Then the screen turns black and according to
the fan noise I think the cpu get in some kind of infinite loop. It
doesn't power off.

2. After an acpi suspend to ram (echo 3 > /proc/acpi/sleep) the computer
never wakes up. It does not matter if an x server is running or not.

I hope this wasn't answered on the list before. Please point me to some
docs if there are any.

Thanks,
Marc

for this issue you might want to follow
http://bugme.osdl.org/show_bug.cgi?id=2183
and see the duplicate at the end. Then you will find a patch:
"hwsleep.c revert part of v1.23 introduced cond. when S5".

I experienced the same problem on my Centrino ASUS M6842NWH.

I tried this patch with no success and then I found that the problem in my case
is completely different: I disabled APIC support in the kernel (not even
compiled) and then I've clean shutdown.

So you've 2 tests:
- - Hartwig's patch
- - disabling APIC support

Thx, bye,

Thanks guys for your help!
Disabling APIC support fixed the issue for me (now I have to find out,
what stuff will not be working because i've disabled apic...)

For the other issue, the notebook not wakeing up after suspend to ram,
nobody has any hints?

greets,
Marc
