Zdravim Vas, pri kopirovani z DVD mi to ide v Opensuse 13.2 velmi pomaly a jedno jadro CPU je tym plne vytazene. Je toho na forach viac, no okrem uistenia ci DMA bezi (u mna taktiez hlasi dma ok, ale performance podla hdparm i realna jasne ukazuju na nieco ine a asi v jadre ?) som nenasiel ziadne riesenie. /etc/sysconfig/hw/ide zjavne nema uz ziaden vplyv - cokolvek tam dam tak to ide formalne na najvyssej dma, no realne asi nie. Prosim ak niekto viete napiste ku tomu par slov.. PS:Nejde podla mna ani o RIPLOCK drive feature. Pri prechode na rychlejsi stroj sa to sekne na vyssej rychlosti, zodpovedajucej opat 100% CPU load pre jedno jadro. (Pomalsi stroj C2D E7400, Rychlejsi Xeon X5450).
