It seems to me that 300 seconds freeze before entering hibernation and upon wakeup from hibernation/suspend is due to ACPI error. Here is a piece of dmesg log upon waking up from hibernation:
[ 809.010089] ACPI: Waking up from system sleep state S4

I've included decompiled DSDT table from Acer Aspire One 721-128ss BIOS as it can be helpful. If any further information or testing is needed I'll be glad to provide it.
