The error reported in the "dmesg | grep PM" is "Device 3:0:0:0 failed to suspend async: error 134217730" The dmesg log is : [ 767.677738] PM: Syncing filesystems ... done. [ 768.725558] PM: Device 3:0:0:0 failed to suspend async: error 134217730 [ 768.842476] PM: Some devices failed to suspend [ 772.386385] PM: resume of devices complete after 3552.271 msecs So, when I try to suspend-to-RAM, the PC goes sleeping and wake up immediately due to a device (which one ?) that failed to suspend. I tried also the "pm-suspend" in command line, same result. Instead, the suspend-to-hisk (hibernate) works perfectly. If I reboot to the Ubuntu 12.10 kernel (kernel before upgrade, version 3.5.0-27-generic), it works prefectly again. I tried with this kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-raring/, the problem is still there. Kernel version is "Linux pc-fixe 3.8.0-19-generic #30-Ubuntu SMP Wed May 1 16:35:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux" and everything is up-to-date. Ubuntu version : Description: Ubuntu 13.04 Release: 13.04 I attached the log files corresponding to the problem (kern.log and pm-suspend.log). Don't hesitate to ask if more information is needed or I must run some tests.
