I have 2.6.1 + the 2.6.1-specific patches + core patches. It suspends without difficulty, but on boot, it says it couldn't read a part of the resume data (a "chunk", iirc). The status bar doesn't make much progress. I tried hdparm -W 0 right before the call to hibernate (in a script). But I still have the problem. When should hdparm be called?
