Inspiron 6000 / ACPI S3 / PCI-X problems?

Inspiron 6000 / ACPI S3 / PCI-X problems?

[Michael (Micksa) Slade]

 I think this is my first ever post to l-k.

I'm scared.

I've been trying desperately to get suspend-to-ram working on my new 
inspiron 6000.

So far, the patch at

http://lkml.org/lkml/2005/5/23/116

Got the hard disk working after resume, and at least the b44 ethernic 
keeps working, but the display doesn't.  No amount of vbetool voodoo 
seems to bring it back up

Turns out the PCI config for the card gets trashed:

http://knobbits.org/archived/2005-06/lspci-i6000-after

It's an ATI radeon M300, on a PCI-X bridge I think.

Is this a kernel issue or an X issue?  I vaguely recall some pci config 
save/restore hack floating around somewhere, should I try that?

This is ubuntu breezy, using xorg and kernel image 2.6.11.93-1.1

PCI-Express (PCIe), not PCI-X.

The i6000 is very similar internally (identical?) to the i9300.
I have a Dell Inspiron 9300 and *everything* is working perfectly with Linux,
except for the SD-slot (no driver, no datasheets).

Try my suspend script and other (K)Ubuntu changes:  http://rtr.ca/dell_i9300/

Cheers

Thanks.  No dice :(  Apparently the models have some differences 
internally :/

Do me a favor?  Grab lcpsi output under normal conditions, and also just 
between the resume and the "vbetool post"?

Whose job should it be to restore the PCI config? (assuming that's the 
problem)  Which code should I start hacking?

I'll bluddy well scoff the PCIe spec if I have to!

Mick.

Same here. Make sure you suspend from within X, this seems to be
"better".
