The problem occurs also with plain echo 'mem' - I've already checked before. Just resently I've discovered that actually I've had some serious problem with CONFIG_DEBUG_PAGEALLOC option. Unsure if this thing could be related to my deadlocking problem during suspend - I'll watch, if the freeze will be still ocurring even without this option.
I'll make probably a separate post about my debug option problem.
