I was able to fix the same problem without using initrd.
In the menuconfig
device drivers->ATA/ATAPI/MFM/RLL support
   Support for SATA (deprecated; conflicts with libata SATA..
is disabled.
device drivers-> SCSI device support
   SCSI device support 
compiled in the kernel (*)
device drivers-> SCSI device support-> SCSI low-level drivers
   Serial ATA (SATA) support 
compiled in the kernel (*)

Using these configurations it worked for me very well. Wish it helps you too.
