it seems the same on my M3N, I attached some mails I already sent to
this list, which solved the problem for S4, maybe you could give it a
try. IMHO is still an Intel 855GM problem.

As soon as I'll come back home, I'll try again on my M3N.

Thx, bye,

[the following is for ASUS L3800C]
Same here for USB (actually, unloading {usb-,}uhci suffices, 2.6 doesn't
hang though). ALSA doesn't seem to care in my case.
About the shutdown: it is likely that a PWRF event is issued after resume
like in my case, kill acpid prior to suspending and see if it makes any
difference (I reported the PWRF problem here a while ago, but have
received no feedback so far).

Kill X and unload AGP or use Nigel's patches from swsusp.sf.net.

ok, I tried the following without the AGP/DRM modules (specifically,
'agpgart', 'intel-agp' and 'i830'):

- - PM_DISK > the OS enters ok in S4, but the resume process doesn't work
(not with resume=/dev/hda6, not with pmdisk=/dev/hda6 neither without).
I got a resume on my ext3 partitions, but the swap isn't lost

- - SWSUSP > it works! But, obviously, as I wrote above, without the
AGP/DRM modules. Anyway, I got a perfect S4, a perfect resume and after
the resume I can successfully resume or shutdown :-)
