Jeff, Jesse, please check one thing for me. Please boot 2.6.25-rc2 (or better, the current head of the Linus' tree) with no_console_suspend and try to do the following: # echo 8 > /proc/sys/kernel/printk # echo core > /sys/power/pm_test # echo disk > /sys/power/state (that will run a test of the freeze/unfreeze code without creating the image) and then # echo mem > /sys/power/state (that will run a test of the suspend/resume code without actually suspending). I'd like to know if that works.
