thanks, Pete.
I applied the patch, it can mount the root now. Such a delicate patch.

Have you made the HPT371N working for 2.6 tree?  When I want to
compile in the hpt366.c, the kernel will hang up right after it found
the disk drive:

Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
HPT371: IDE controller at PCI slot 0000:00:0b.0
PCI: Enabling device 0000:00:0b.0 (0000 -> 0003)
HPT371: chipset revision 2
HPT37X: using 33MHz PCI clock
HPT371: 100% native mode on irq 5
   ide2: BM-DMA at 0x1000-0x1007, BIOS settings: hde:pio, hdf:pio
   ide3: BM-DMA at 0x1008-0x100f, BIOS settings: hdg:pio, hdh:pio
hdg: IBM-DTTA-350840, ATA DISK drive

hang up ................ :(
