2.4.18-alt6master-smp

в принципе могу попробовать на сизифном 2.4.20-smp-alt0.8, но малость страшновато - рабочий сервер.

Чего то не нравятся мне эти сообщения:
пахнет отсутствием оптимизации.

raid5 - soft raid level 5 на трех одинаковых scsi дисках. 
Отчего он может постоянно скакать по разным cache buffer size?

Я сейчас все сервера стащил на 2.4.20-alt0.8: по крайней мере в
одном из известных мне мест откатились с 2.4.18-alt6master-smp
на 2.2.22-secure.
