My own experience with this is that if you have to enable DMA using hdparm, then something is lacking in or even wrong with your kernel. This can be quite harmless, but it could be a sign that your system can't handle that sort of DMA. Perhaps it's time to recompile that kernel or get a new board. When I used my previous kernel, which worked nicely on a VIA-based board, on a SiS board, DMA was invariably disabled at boot time. I would force DMA using hdparm, and soon enough I would get disk read errors. Recompiling and enabling (I suspect) "CONFIG_BLK_DEV_SIS5513=y" let me boot with DMA enabled. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
