Проверю позже т.к. то было на amd64 и ядро там xen-vserver. Кроме того ядро уже обновлялось в дистрибутиве. Проверю и там только попозже. P.S. В ядре точно есть патчи для JFS. P.P.S. Если надо что-то посмотреть/протестировать - говорите куда копать. 53797 2 mrkooll 2007-08-07 20:01:30 +0400 Небольшая заметка.
