Wyrwi li dobre bez wyprosniq patch na kernela? Imam predwid, che pri chastichen
upgrade na debian 2.1 na unstable i na men mi praweshe absolutno syshtite
problemi - neochakwani segfaults, naj-neweroqtni greshki, nqkoj neshta
(mysql-server, apache) prosto ne trygwaha i t.n. Ako imash wyzmovnost, naj-dobre
si go naprawi izcqlo na unstable (izoshto ne e "nestabilno", s takyw debian sym
ot 2 meseca weche). Towa go otdawam na nepylni dependencies, drugo prosto ne mi
idwa na akyla, no fakt e, che winagi taka stawa.
Syshto probwaj da naprawish [sl]trace na nqkoq programa, koqto gyrmi - ponqkoga
mnogo pomaga za otkriwane na podobni problemi.
