SATA终于好了

终于好了。原来我在kernel编译时选择了下面这些：

Device Drivers --->ATA/ATAPI/MFM/RLL support  --->
[*]     Support for SATA (deprecated; conflicts with libata SATA driver)

Device Drivers --->SCSI device support  ---> SCSI low-level drivers  --->
[*] Serial ATA (SATA) support
<*>   Intel PIIX/ICH SATA support  


呜~，它都说conficts了，我还选……
后来把Support for SATA去掉后就快了，用/dev/sda?访问
