Ho un server di rete con una connessione wireless che usa ndiswrapper (la schera userebbe i driver rtl8187 ma attualmente non funzionano con i kernel recenti).
Ultimamente mi si sconnette spesso e al riavvio mi trovo nei log del kernel questi errori:
Code:

Uso un kernel 2.6.21-r4 (gentoo-sources) e una connessione wpa.

Sono già dovuto passare dalla versione 1.44 alla 1.45 (~x86) perché la precedente aveva problemi con la nuova funzione tickless (o come accidenti si chiami... mi sa che la rimuovo) del kernel 2.6.21 e dava un bug che troverete cercando "ndiswrapper NOHZ" nella ricerca globale.
Ora anche la 1.45 da problemi? Non è che il kernel 2.6.21 è un tantino instabile?

Nessuno ha sperimentato problemi con ndiswrapper?

pare che dia questo errore ogni volta che parte mldonkey... mmm... che può essere? Soprattutto: perché l'altro giorno non lo faceva (non ho cambiato niente)?
