Kernel Bug Tracker – Bug 15695
calling pm-suspend freezes system

The title says all. The graphics system is switched to the console, then everything freezes without a trace in any of the log files. This is the first kernel of the 2.6.34 series I'm able to boot. Running 2.6.33-26 this problem doesn't exist.
Note that I *suspect* that it is a problem with the graphics driver (since usually pm-hibernate on 2.6.33 fails with similar symptoms).
Please tell me how to improve this report, if possible or necessary.
A typo: My current running system is 2.6.33-27.
BTW, I'm not even able to do a normal shut down; the last step, this is, switching off the display, fails.
Running 2.6.34-rc6-28-pae (from openSuSE's factory kernel), both pm-suspend and pm-hibernate work again.
Yes, disabling FBC (frame buffer compression) on 945GM (upstream code change) fixed the issue.
