Hi, all, I am porting linux to our mipsel system. I make a ext2fs system on my intel system, then copy root file system to this hard disk. Finally I attach this disk to our mipsel system. Our system use Acer Lab Ali1535D south bridge. When linux kernel start, it can report disk volume information and partition information, and root file system is mounted. But the time is very long, and I could not get any ide0 interrupt. The time is wasted on schedule(), but if I use ramdisk, the system is running fast. I think the problem is my IDE controller driver or hardware problem. Does some one know the reason? If so, please help me. Thanks!
