Dotaz: suspend2 - kolik pameti potrebuje?

[xsmejka1]

Ahoj.
Mate nekdo zkusenosti se suspend2, resp. s hibernaci pres suspend2? Mam pocitac s cca 400MB RAM, jadro 2.6.20, suspend2 2.2.9.7, hibernace je nastavena do jinak nevyuzivaneho swapu (>500MB). Pokud nejsou nastartovana xwindows, hibernace funguje v poradku. Pokud jsou jen spustena xwindows (xorg 6.9 + fluxbox) hibernace jeste funguje, avsak staci par terminalu a opera (volne pameti je stale 256MB) a hibernace se nezdari:

Suspend2: SwapAllocator: Signature found.
Suspend2: Resuming enabled.
Suspend2: Initiating a software suspend cycle.
suspend_userui: program not configured. suspend_userui disabled.

Unable to free sufficient memory to suspend. Still need 9065 pages.

Na strankach suspendu se pise, how it works:
1) Stop all processes. If some processes can't be stopped, abort.
2) Eat memory. At this stage we check if we have enough memory to save the image and meet your specifications for maximum image size. If necessary, we unfreeze the processes, eat memory until we think we have enough and then try again from step 1.
3) Suspend drivers. This accounts for the screen briefly going blank on some computers.

Zrejmne tedy suspend thinks ze memory jeste nema enough, a skonci na kroku 2.
Neznate nekdo zpusob, jak ho donutit aby se uskromnil? Je nejaky figl, nebo nastaveni, ktere jsem prehlidnul? 256MB se mi zda pomerne dost na to co ma suspend udelat. Rovnez si vsak nevzpominam, kde bych definoval nejake specifications ohledne maximum image size.

ja tom mam nastavene takto aj ked mam 2G ram :o)
Ked tam je nastavene nocache tak zrazi buffre a dikovu cache na nulu a az potom zacina hibernacia. Ked je tam nejake cislo tak sa snazi zrazit image na tu velkost (vycistenim cache/buffrov alebo poslanim app do swapu)

bdw. mam 2G ram a presne tolko velky aj swap. obcas mi to hadzalo podobnu hlasku ked som nemal nastaveny ten parameter a aj dlho trvalo odhibernovat

Tak to nebylo tim.
Problem je v tom, ze mam 2 swapy, jeden maly ktery zatim stacil, a druhy vetsi, ktery jsem vytvoril prave kvuli hibernaci aby se do nej vesla cela RAM. Nenapadal me duvod proc by ten druhy mel byt taky swapon-nuty, kdyz je to jen nahrada specialniho odkladaciho souboru, nicmene kdyz jsem tak udelal funguje to. Kdyz se nad tim ted zamyslim, uz je mi to jasne.
jinak dik za navedeni na imagesizelimit, s tim jeste zalaboruji.

Zkus nastavení ProcSetting full_pageset2 1, pak by mělo stačit cca 10MB volné paměti.
