Ok, it seems to work with a 2.6.3 kernel; highmem and preemtion disabled.
Can I ask you how you have USB enabled? Compiled into the kernel or as 
modules?
I could have sworn I erad something about ACPI swsusp and USB conflicts.

Do you use swsusp constantly, and do you find reliable so far?

S3 partial sucess on centrino 855GM

[Alexei Gilchrist]

The following was pointed out to me on another list and I've verified it
works on my Panasonic W2 (centrino, 855GM):

kernel 2.6.1 or 2.6.3, XFree86 v4.4, using VESA driver for X, S3 will
work, the screen will switch on again using a combination of Ctr-Alt-F8
and Ctrl-Alt-F7.

It doesn't work from a console, or using the i810 driver. Also the
network card seems dead afterwards and a reboot will hang the machine.

Still, it's a partial success for reviving a dead screen that seems to 
plague several centrino laptops.

Anyone with this problem care to check other versions of XFree86, and
verify it on other laptops? 

I don't know if it's possible to take whatever initialisation the VESA
driver is doing and always executing it on resume?

cheers,

Alexei
