...ds (power LED blinking) but does not resume in runlevel 3 / multi-user.target. When it locks up, the machine is unresponsive to ping/ssh so it's not just a blank screen. Unfortunately, the only applicable guide I found on troubleshooting this is for Ubuntu, which requires the kernel to support pm_trace which isn't found in /sys/power. Since there is a big red warning on centos.org about building/compiling my own kernel to add functions, I'm wondering if there are any alternative method to troubleshoot the issue on CentOS.

...re crashes while watching videos. I have also confirmed that suspend/resume works after I unload the nouveau driver. I use the following commands: echo 0 > /sys/class/vtconsole/vtcon1/bind rmmod nouveau pm-suspend I have also done a test of suspend/resume with Nouveau loaded after activating pm_trace (i.e. echo 1 > /sys/power/pm_trace).

To suspend to ram I use this script, as suggested in Documentation/power/s2ram.txt: #!/bin/sh sync echo 1 > /sys/power/pm_trace echo mem > /sys/power/state When I try to suspend to ram, the screen wents black but the backlight is still on. The laptop is frozen, no interaction is possible, turning it of is only possible by holding the power button down. This is the log for the suspending process via the bootparameters...
