Problemom je ze tato hlaska sa mi pravidelne opakuje v syslogu a potom mi zamrne PC.

Skusal som yaste znovu nastavit zvukovku ale stale to iste. Najde sa guru ;--)

Alebo nejaky len hit kde by som mal zacat popripade, koho by som sa mal opytat. Toto je problem ktory zrejme vyriesi vseobecny problem so zamrzanim SUSE 10.1 s ktorym sa stretava asi kazdy ako tak po fore citam. Ten dovod by sme uz aj mali.

Nemyslím si, že by tento bug mohl způsobit zamrznutí, obzvláště pokud to hlášku háže v intervalu několika minut. Hoď sem prosím výstup skriptu http://alsa-project.org/alsa-info.sh ať vidíme, jakou máš verzi alsy a zvukový HW.

tak tu mi to zamrzlo a rozdiel v case a start syslog je novy boot. Nic ine v syslogu nie je iba ze sa jedna a tuto chybu a pise to stale dokola:

Tu je vysledok toho skriptu vyborny skript, ale nie som z toho mudry, treba sa viac ucit : http://pastebin.ca/1064041

Nemyslím si, že by ten zásek byl způsoben driverem alsy. Ty chyby mají veliký časový odstup. Nicméně od verze alsy 1.0.11 již uplynulo několik let a tisíce změn v kódu. Tipnul bych si, že nová alsy by ti chybu již neházela (ale k záseku by asi stejně docházelo), stačilo by nějaké aktuální jádro. Také se mi občas seká komp, přehřívá se CPU.
