USB zařízení mizí - statická elektřina?

[marshall1727]

dd,

mám 8.04 server s doinstalovaným gdm v serverové skříni kam nejde dát zvukovka. takže jsem si pořídil

ze začátku bez problémů, později vypadávala. frekvence vypadávání ze zvyšuje, tak, že nyní i několikrát za hodinu. v syslogu jsem našel toto:

jediné podezřele, čemu nerozumím je záznam:

Kód: [Vybrat]

Jul 27 14:55:01 akserver /USR/SBIN/CRON[12494]: (root) CMD ([ -x /usr/lib/sysstat/sa1 ] && { [ -r "$DEFAULT" ] && . "$DEFAULT" ; [ "$ENABLED" = "true" ] && exec /usr/lib/sysstat/sa1 $SA1_OPTIONS 1 1 ; })
ale ani tento bezprostředně nepředchází odpojení. předchází např. o 30s i více.

nemáte nějaký nápad čím to může být?

díky

[marshall1727]

myslíte, že by to mohla být statická elektřina?

[fenquick]

Spíš hw problém

[Roman Vacho]

Zkoušel jsi jiný vstup?

[fish]

Nepáči sa mi že NetworkManager pracuje so zvukovou kartou. To sa mi zdá hlavná chyba. Ak tam začne posielať sieťové pakety je jasné že karta zblbne. Hľadal by som týmto smerom.
Vyzerá že HAL považuje túto kartu za sieťovú.

case má jenom dva USB vstupy na předním panelu. zkoušel jsem oba.

děkuji, tohle mi nedošlo. zkusím popátrat.

teď to třeba dělá jenom tak dvakrát za týden. uvidím jestli bude ještě horké a suché počasí a jestli to bude dělat víc.

[marshall1727]

tak nevím, ale asi bych to uzavřel s tím, že to dělá statická elektřina. tu USB zvukovku jsem strčil do půlmetrového usb hubu a za ten zhruba měsíc vypadla jenom jednou.
