Переход на NPTL

Делаю переход согласно руководства http://ru.gentoo-wiki.com/HOWTO_Переход_на_NPTL

Все шаги прошли успешно, за исключением
# emerge glibc

Вот на чем споткнулся:

The bug is not reproducible, so it is likely a hardware or OS problem.

Это моя ошибка в чем-то? Или действительно баг?

P.S. Извините за длинный пост.
