А някъде има ли отзиви, как работи BSD на подобни машини?
Имах същия проблем на един HP Proliant, не помня кой модел точно.
Хората искаха bsd, сложихме freebsd, но така си умираха интерфейсите.

Четохме, прекомпилирахме и какво ли не.
В крайна сметка не се откри причината за проблема, но в  документацията 
за "подържани ОС" пише windows xxx и rhel.
Така че сега на машината се мъдри CentOS и с него няма проблем.

Може да сме пропуснали нещо важно, характерно точно за тези машини, но 
какво, така и не разбрахме.
