Dotaz: IO APIC + hostap + deska M848A (SIS 748)

[xor]

Cau, mam tuhle desku s 5 PCI pozicema, plne obsazenou (4x wifi XI-626) a 1x 4port Tulip. V posledni dobe karty vic padaj a v syslogu se objevuje hlaska:

May 22 20:13:02 voxor kernel: APIC error on CPU0: 04(04)
May 22 20:13:02 voxor kernel: APIC error on CPU0: 04(08)

a vytuh. Distribuce je FC3, vlastni jadro vanila 2.6.10 s povolenym IO APIC, protoze jinak hostap nahodi jenom 2 wifi. Kdyz zkusim pouzit jadro bez IOAPIC - napr. distribucni (nebo APIC vypnu v BIOSu), tak to vypise nasledujici chyby (hostap 0.3.7, 0.2.6 i 0.4.1 delaj to samy):

a zacne ty karty nahazovat s jinym ovladacem (orinoco_pci). Myslel sem si, ze je nedostatek IRQ, ale kdyz ty karty pak zacne nahazovat, takze je probles asi jinde. Ale kde? Btw. chlazeni je vic nez dostatecny. Pokud dotaz patri do fora Zakladni desky, tak to tam klidne presunte. Diky za napady.

Bohuzel ti konkretne neporadim, ale jen neco z zkusenosti. Vseobecne se rika ze maximim jsou 3 626ky v kompu, je to kvuli ruseno uvnitr bedny. Zalezi na tom jak mas volny kanaly. 4portovka tulip si vezme 4 preruseni. Takze je temer nutnosti vypnout seriovy porty, paralelni, usbcko, sekundarni IDE a vse co jeste de vypnout aby se ti uvolnili IRQcka. Posli /proc/interrupts.

Jinak my jsme meli s deskama se SiS cipsetem jen samy potize (typ nevim, ale cpu P-II cca 300), vsechny jsme je vyhazeli. Zkus to taky, treba to pomuze

Cau, to s tema prerusenima je asi spravny vysvetleni. Kolik zarizeni muze sdilet jedno preruseni? Paralelni port, com2 a usb jsou vyply, sekundarni IDE jsem taky zkousel vypnout a nepomohlo to.

vypis s parametrem noapic (nahodi pouze 2 wifi karty):

To s tim rusenim je v podstate pravda, jedna z tech linek je jenom zaloha Ronji.

S tema IRQ se to ma tak, ze nejlepsi je kdyz mas kazdy zarizeni na extra IRQ. Jenze moderni desky jsou blby jak tago a casto davaj vic zarizeni na jedno IRQ i kdyz ma jeste nejaky volny. Vetsinou pomuze to napevno nastavit v biosu.

Pokud mas kvalitni desku (pro routery je to pro me ciste intelacky reseni, nejlepe compaq sesatva tak se mozna nemusi nic stat. S prekvapenim jsem zjistil ze v jednom routru (2x626, 1xe100) vsechny 3 karty jedou na stejnym preruseni a je to stabilni.

Ale zkusenost ukazuje ze jak se ti sdili preruseni tak jde stabilita do haje. Typickym prikladem budiz tv karta+grafika. jakmile se sdili preruseni, za 5 minut je komp tuhej.

Tak sme to vyresili nasledovne: vypli jsme integrovanou sitovku a prehodili kabel do 4 portovyho Adapteca. to zpusobilo, ze jsme mohli vypnout APIC, pritom vsechny XI-626 se nahodej dobre. jadro ted startujem s noapic nolapic pci=noacpi. router je naprosto stabilni, zajimavy je, ze prikaz top ted ukazuje software interrupts 0%, pred tim to bylo porad 5-30% podle zatizeni AP. podrobnosti tady pandora.idnes.cz.
