ext3, quota, nfs, 2.4.17, oops (LONG)

[David Tok]

Hezky den,

  mam problem, jeden nepatrny lokalni server (P3, 450MHz, 256MB RAM, 
8Gdisk) me jel bez problemu asi tak 40 dni an 2.4.14. Pak jsem provedl 
upgrade jadra na 2.4.17 a asi 2 dny na to mi zacal kernel vyvadet pokud 
jsem chtel zapsat na ext3 parice. Chctel bych zjist, kde je presne 
problem. Daval jsem to za vinu ext3, ale na podobne priznaky me sletel i 
jeden router a tam je 2.4.14 a ta mi jede vsude jinde v pohode. Na jinych 
strojich s obdobnou konfiguraci me funguje i 2.4.17. Nevim, hledam 
problem, moc z toho chytry nejsem, potrebuji jenom najit ktera cast jadra 
dela potize.

diky,
