Dotaz: Pomalé CPU

[ZeXx86]

Dobrý den .. Chtěl bych se zeptat, kde může být problém, jestli-že mám Gentoo Linux 2006.0 na pc Celeron D 1,7Ghz / 512MB Ram značky IBM (desktop) - sloužíci jako hw server, který musí jet non-stop .. Tedy problém je v tom, že se asi po 3 dnech pc razantně (najednou) z ničeho nic spomalí, včetně času na pc .. Odhaduji spomalení na 60x .. tj za 2 týdny chodu mi takhle ukazoval nekdy i uptime 3dny .. Spomalení se projevuje jen v některých činnostech (každém programu ale jen v určité části) .. Příklad, spustím libovolný herní server, např CS1.6/CSS/ET/Prey apod, u těch se program doslova zastaví po načtení mapy, kdy už by se mnělo dát připojit, server teoreticky je spuštěn, a dá se na něho připojit, protože ten "lag" trva cca 30-50s a 2s jede normálně .. Takto se to pořád opakuje .. Některé jednoduché servery fungují pořád správně .. Ale např DC++ hub posíla clientovi informace o uživatelích asi až po minutě .. Takhle bych asi shodnotil chod programů, jinak připojení přez ssh se mi zdá stejně rychlé, i když možná prace se soubory je pomalejší .. Když celý hw server restartuji - když je "spomalený" - tak se tímto vyřeší problém opět na 2-3dny .. Ovšem než-li ho restartuji, oběví se drobné komplikace s bootovaním .. PC občas vyhodí hlášku že nemohl najít žáden systém k bootu, nebo se spoustení pc (ůvodní screen) drží na obrazovce 20s, a po té mi vypíše info o HW, a pro normální nabootování mám stisknout F2 a poté SHIFT+S, potom už systém naběhne v pořádku .. Jinak celé PC je velmi dobře chlazeno, chlazení je spínací / regulují se otáčky podle teploty = opravdu velmi tiché .. Celé PC na mne působí kvalitní konstrukcí i vybavením .. Myslím, že problém bude někde mezi HW a SW, zkusím pořádně otestovat RAM, i když si myslím, že jsou v pořádku .. Nakonec přidávám log s dmesg:

Zkus vypnout apic , anebo prohledej google.

[eh]

anebo v biosu zapnout compatible mod ... rozhodne neco s biosem to vyresi...

[houska]

co rika smart na disky?

[Mrkva]

Videl bych to na pameti... Pokud je v systemu 512MB RAM, proc dmesg hlasi jen 250MB?

[ZeXx86]

Zkusím tam dát přímo 256MB Ram, nevím proč ale od jedné doby co bylo strašné horko, se 512 chová jako 256, ale to byla ram jeste v jinem pc, ktery se dost zahrival .. ok, zkusim vypnout apic, ale musím přijit na to jak :)

[secido]

aha, ja zadal

a jinak jak poznam ze apic je off ?

V tom vypise je

takze si pohladaj nieco o tom na google. Alebo poexperimentuj, ci je to cele ovplyvnene zapnutim/vypnutim APIC/ACPI. A posledna vec "tiche" nemusi znamenat "dobre chladene". Obzvlast pri takom to evidentne "prehriavajucom sa" chovani, by som to odskusal s nejakym vetrakom bez regulacie, ale zato poriadne beziacom.

[ZeXx86]

Kdyz si sahnu na passive vetrak od cpu, tak je uplne chladny, ma pokojovou teplotu

[ZeXx86]

Našel jsem na webu:

I picked up a surplus IBM Net Vista 8308 last week (ICH4/82801DB chipset), and lo and behold, I saw the same clock weirdness you reported. There's a smattering of similar reports on the web spread across all distros. The best description of the issue is in the source code itself. Take a look at the file arch/i386/kernel/timers/timer_pm.c.

It seems to keep time okay if I boot with noapic, but I'm trying a different option at the moment: clock=tsc. I'll let you know if it works out.

Tento problém mají zřejmě stroje od IBM

[Käyttäjä 11133]

Proč to dáváš do <pre></pre>?

[ZeXx86]

Asi zvyk .. Jinak dal sem tam ten parametr noapic a uvidime co to udela za 3dny Zatim díky za Vaše reakce

[Zdeněk Burda]

odmazal jsem pre tag

[Semo]

Ak na pomalom a regulovanom vetraku ma pasiv izbovu teplotu, tak je IMO niekde chyba. Problem je v tom, ze pocitac nepocita pasivom ale procakom. Nechce sa mi verit, ze by Celeron 1,7 mal izbovu teplotu. Ja na tvojom mieste by som sa pozrel pod pasiv, ci ma dobry teplovodivy kontakt s CPU.

Skus na tom serveri pustit nieco jednoduche, ale hodne vytazujuce. napr. v jednom terminali si pusti

cat /dev/urandom >/dev/null

a v druhom

for i in {1..1000}; do echo -n "$i "; cat /proc/acpi/thermal_zone/THRM/temperature; sleep 1; done

pripadne cez lm_sensors si periodicky pozerat teplotu. Ak ti teplota nefunguje, tak aspion bedes sledovat, ci vypisuje cisla po sekunde.

[ZeXx86]

hehe, vždyt jsem instaloval na tom celé Gentoo, několik distribucí ... Jsem si jist, že teplotou CPU to není, v tom case je výborná kumulace vzduchu, opravdu jde do vnitř a pak zpět, žádná čast HW se tam nijak nehřeje .. Jinak ten passive neni zrovna nejmensi a ty vetraky taky ne .. Jinak muj CPU Athlon 64 5200+ se hreje na 30C pri zatizeni, normalka to je tech 25 stupnu .. Mam jen lepsi chladic ..

[ZeXx86]

Takže zda se, že problém je vyřešen Děkuji Vám mnohokrát (parametr noapic pomohl)
