I sent this to the -devel list, but this is probably more appropriate.

Subject: [Mactel-linux-devel] No luck suspending Macbook non-pro
Date: Tue, 23 Jan 2007 19:48:04 -0200

With an unhealthy dose of jealousy I've been reading the success stories
of many suspending the Macbook. I have no such luck.
After trying a lot of different patches and kernel configurations, I am
almost ready to give up. I just can't get it to work. Before giving up
altogether, I thought maybe I'd ask for help in debugging this problem
and eventually getting suspend to work on my box.
The box is a Macbook non-pro (1.83GHz) and here's what I've tried, so far:
o Vanilla kernels 2.6.18, 2.6.19.2 and 2.6.20-rc4
o Same as above with mactel patches
o Suspending by echoing mem to /sys/power/state
o uswsusp's s2ram(1)
(1) I booted with init=/bin/bash and tried several combinations of
arguments to s2ram
What happens is that the display is turned off correcty but then the
computer freezes completely. I have to hold the power button down for a
couple of seconds and then power the macbook back on.
s2ram seems to have the laptop in its whitelist. Here's what it says
about my box.
[EMAIL PROTECTED]:~# s2ram -n
Machine matched entry 2:
sys_vendor = 'Apple Computer, Inc.'
sys_product = 'MacBook1,1'
sys_version = ''
bios_version = ''
Fixes: 0x4 VBE_SAVE
This machine can be identified by:
sys_vendor = "Apple Computer, Inc."
sys_product = "MacBook1,1"
sys_version = "1.0"
bios_version = " MB11.88Z.0061.B03.0610121324"
See http://en.opensuse.org/S2ram for details.
From init=/bin/bash I can actually see something happening, although I
don't know whether this is much help:
Switching from vt1 to vt1
Calling save_state
Allocated buffer at 0x2010 (base is 0x0)
ES: 0x0201 EBX: 0x0000
[ 23.800000] Disabling non-boot CPUs ...
[ 23.812000] Cannot set affinity for irq 0
[ 23.916000] CPU 1 is now offline
[ 23.916000] SMP alternatives: switching to UP code
[ 23.916000] CPU1 is down
[ 23.916000] Stopping tasks ... done
[ 23.916000] Suspending console(s)
After this, nothing else happens. I see the little hardware cursos
blinking but the box doesn't respond. A hard reset is required...
I am writing this in the hope that I am doing something obviously wrong
or that someone may give me tips on how to debug this.
Thanks,
-rst.
