Thank you. I am not pro in this questions, but now we know that this solution helps to solve the problem! Thank you for your answer. Btw, I have found some information about libata.dma here http://www.kernel.org/doc/Documentation/kernel-parameters.txt: libata.dma= [LIBATA] DMA control libata.dma=0 Disable all PATA and SATA DMA libata.dma=1 PATA and SATA Disk DMA only libata.dma=2 ATAPI (CDROM) DMA only libata.dma=4 Compact Flash DMA only Combinations also work, so libata.dma=3 enables DMA for disks and CDROMs, but not CFs. Thus this parameter enables DMA on only on disks, not CD/DVD rom. I have writen to VIA support team about this problem, hope they will answer on e-mail or in https://bugzilla.kernel.org/show_bug.cgi?id=44111
