Description of problem: I first installed Fedora on my Lenovo v570 laptop a few days ago. The installed kernel was kernel-3.11.10-301.fc20.x86_64, where suspend worked without issues. I was able to close the laptop to suspend, or to use pm-suspend to suspend and wake up. Suspend no longer seems to work on kernel-3.16.6-200.fc20.x86_64; the power light no longer blinks on suspend, and waking up with machine by opening the laptop or hitting a key does not work. Version-Release number of selected component (if applicable): kernel-3.16.6-200.fc20.x86_64 How reproducible: Every single time using kernel-3.16.6-200.fc20.x86_64 Never using kernel-3.11.10-301.fc20.x86_64 Steps to Reproduce: 1. Boot with kernel kernel-3.16.6-200.fc20.x86_64 2. Close laptop / do sudo pm-suspend 3. Open laptop / hit keys on keyboard Actual results: Display is black (doesn't appear to be on). Cannot open VTs, cannot login to any session or display previously suspended session. Expected results: Screen lights up and allows user to use machine. Additional info:
Created attachment 948299 [details] dmesg post suspend After I ran: sudo sh -c "sync && echo 1 > /sys/power/pm_trace && pm-suspend" the machine appeared to suspend (screen turned off), although the power light did not begin to blink as it does not the previous kernel. Attached is the dmesg post reboot, where I was unable to find any "hash matches".
