Коллеги. Как то ране не встречалась подобная проблема. Вероятно потому что как то не часто приходилось ставить FreeBSD на всякое "левое железо".
Суть проблемы - медленно работает дисковая система.

Добавлено: Соответственно как только система что то пишет, так чутли не колом встаёт. Особенно это заметно при копировании больших файлов.
В данном случае система на gmirror, но абсолютно такая же картина если просто один диск.
