I follow Debugging hibernation and suspend at [1], where i did tests via /sys/power/pm_test. The first i try the "freezer", which works, then i try the "devices" option, where the same problems happen, then it seems. IIUC, the problem is with suspending the devices. Now the question is: which device? Any help is welcomed :) [1] https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt -- Slavko http://slavino.sk
