I can't resume from suspend and I have an idea that Zram or prefetch cause this. I have a blinking cursor when trying to resume. I'd like to try turning zram off, but I was unlucky to find the command using google

Running dmesg|less i have seen the following lines

nautilus[2057]: segfault at a8 ip 0000000000486d44 sp 00007fff7d448e10 error 4 in nautilus[400000+159000]

running swapon:

 swapon -s

Look at /var/log/pm-powersave.log. It will show you what your system does as it enters and leaves suspended state. See man pm-action and dpkg -L pm-utils. Diligent reading will show you how to add a script to the process, or simply mask one of the existing scripts. Oh, yes, read the scripts to see what's really going on.
