This problem often happens when you forget to enable a proper chipset
type in the section ATA/IDE ... 
        in make menuconfig


You can find out the chipset type  by lspci:

stavel@4[stavel]$ lspci 
00:00.0 Host bridge: ALi Corporation M1671 Super P4 Northbridge [AGP4X,PCI and SDR/DDR] (rev 02)
00:01.0 PCI bridge: ALi Corporation PCI to AGP Controller
00:06.0 Multimedia audio controller: ALi Corporation M5451 PCI AC-Link Controller Audio Device (rev 02)
00:07.0 ISA bridge: ALi Corporation M1533 PCI to ISA Bridge [AladdinIV]
                                        ^^^^ this is my chipset ^^^^^
