Hi!

All right. It works! :-) Thank you very much!
I'll describe how I tested: So far you sent 3 Patches to the list. As I couldn't apply the second one to my v2.6.26-rc4 tree i had to get git and then your tree. Now I have a git working tree with two branches *master* and *pavel*, corresponding to torvalds/linux-2.6 and pavel/work respectively. I made *pavel* the current branch and issued the following command:
git diff v2.6.26-rc4 arch/x86/kernel/aperture_64.c \ arch/x86/kernel/k8.c \ arch/x86/kernel/pci-gart_64.c \ drivers/char/agp/generic.c \ include/asm-x86/gart.h \ > /home/pat/suspend-vs-iommu.patch
The result is on http://zefir.890m.com/dmesg/
I applied this patch to my old v2.6.26-rc4 tree and recompiled a new kernel there *, put it in place and rebooted. I suspended several times since then and put a kernel log of one normal boot process with suspend from console while X is running (radeonhd) on the site mentioned before.
I'm running debian testing / ubuntu hardy mixed system and used kernel .config from linux-headers-2.6.25-2-amd64.deb (debian unstable) with "make oldconfig" and defaults on new options.
The diff is nearly 500 lines long, but i it could be narrowed, I guess. For me it works perfectly like this though. If you want me to do any further tests, just say so. I'm trying to get to know git a bit better and hope to be able to help again sometime. It's great fun! :-)
Cheers
* I get "ACPI: Unable to turn cooling device [ffff81012fa5cdd0] 'off'" every two seconds and "fancontrol" isn't working any more... going to send a acpidump to the acpi group. Maybe i'll find out myself as well... investigating. Not sure if it's caused by the patch.
