Comment 9 for bug 130979

I'm also experiencing exactly the same problem as mentioned in the first description, although I only have one core :P

A brief tour of what I did/had:

Using radeon driver, with some settings (in acpi-support), I had suspend working flawlessly.

Afterwards, I've tried to install the fglrx driver but suspend stopped working.
I changed a few settings, but still no good.

I uninstalled the fglrx driver and reverted to the original working settings but now I'm experiencing this bug.

Worth of mention, is that I have
SAVE_VBE_STATE=false
in /etc/default/acpi-support

so I wonder where vbetool is being called.

My hardware:
Acer Aspire 1694 WLmi
Centrino Sonoma 2.0Ghz
Ati Radeon X700
kernel 2.6.22.9
Ubuntu Gutsy
