I have an i686 desktop (dual core 2GHZ Pentium 4), on which suspend and hibernate have not worked properly since sometime in the 3.1 kernel series. This system has 4GB RAM and uses the PAE kernel. Under F16, I kept updating the kernel and finding each time that suspend and hibernate did not work, and so kept running the older kernel. Eventually I had to move to F17. What happens with the newer kernels is, if I suspend, the machine appears to suspend (last line on the screen is the one about "suspending console, set no_console_suspend to debug" and then it hangs (never powers off). Of course if I power it off manually, the suspended image is lost and it reboots from scratch. If I hibernate it, it does write the hibernate image to disk, prints the "suspending console, set no_console_suspend to debug" line, and again hangs without powering off. If I power off the machine with the power button, on reboot it does resume properly from the hibernate image, so I think the problem is just that it's no longer powering the machine off after suspend/hibernate is complete. The BIOS settings have not been changed from when it was working. This is similar to some other threads I've seen here, but ironically, in my case, the F17 kernels hibernate and suspend just fine on a pair of x86_64 laptops I have (one Dell and one Sony VAIO). It's only the desktop where they don't work. I'm hoping, of course, that somebody will have a magic boot time kernel parameter recipe I can try that might work, or failing that, a pointer to some documentation on how to debug suspend/hibernate problems.
