debug resume from hibernate

Hi, this is puzzled me a lot. How to debug the resume failure after hibernation?

I added no_console_suspend in kernel boot option; in tty2, I ran a series of pm_test sequence up to core -> /sys/power/pm_test and reboot -> /sys/power/disk. dmesg all shows the correct/success log. However, when I echo none > /sys/power/pm_test; echo reboot > /sys/power/disk; dmesg > dmesg.log; system will be back but not responsive to the cmd: dmesg.log will not be created and I saw some message 'io error' on screen and it passed by quickly. this leaves me little chance to see what is really going on for a real resume.

My kernel is 3.1.9-1.fc16.x86_64. I have Nvidia FX 580 and use Nouveau driver.

Any suggestion to make hibernation work or how to debug in the resume process?

Thank you.
