Unfortunately, it is quite common out there. I need to somehow keep those bug reports off my mailbox.
Okay, this should be enough:
Q: What information is usefull for debugging suspend-to-disk problems?
A: Well, last messages on the screen are always useful. If something is broken, it is usually some kernel driver, therefore trying with as little as possible modules loaded helps a lot. I also prefer people to suspend from console, preferably without X running. Booting with init=/bin/bash, then swapon and starting suspend sequence manually usually does the trick. Then it is good idea to try with latest vanilla kernel.
"Known problematic" modules are; be sure to unload them before suspend: - DRI being used (3D acceleration) - Firewire - SCSI
