Do not suspend consoles? PM_TRACE (this > won't help since it completely resumes, I guess)? First, you can try s2ram if you haven't done it already (http://en.opensuse.org/s2ram). It may help to get your video back after the resume. If you have a COM port, it is also possible to use a serial console throughout the suspend/resume cycle. > This is blindly written dmesg after resume.

I'm not an ACPI expert, it won't tell me a lot, but perhaps you should add linux-acpi to the Cc list. ;-) > Should I test 2.6.20 with minimal config? I think it's better to try the -mm with the minimal config. Greetings, Rafael -- If you don't have the time to read, you don't have the time or the tools to write. - Stephen King
