There are issues related to suspend/resume. It looks like I can successfully enter mem mode, however when I trigger one of the wakeup sources I'm not able to resume successfully. #echo mem > /sys/power/state PM: Syncing filesystems ... done. PM: Preparing system for mem sleep Freezing user space processes ... (elapsed 0.001 seconds) done. Freezing remaining freezable tasks ... (elapsed 0.001 seconds) done. PM: Entering mem sleep PM: suspend of devices complete after 53.008 msecs PM: suspend devices took 0.060 seconds PM: late suspend of devices complete after 1.924 msecs PM: noirq suspend of devices complete after 2.604 msecs Disabling non-boot CPUs ... CPU1: shutdown CPU2: shutdown CPU3: shutdown Enabling non-boot CPUs ... CPU1: Booted secondary processor CPU1 is up CPU2: Booted secondary processor CPU2 is up CPU3: Booted secondary processor CPU3 is up And then the system hangs there. I have looked through recent patchwork and I cannot find any obvious commits missing from my branch. I'm thinking this must be a known issue and perhaps you can point me in the right direction for what I should look for. Best regards, Bj?rn Erik Nilsen
