Hi,
We are working on the IDE/ATAPI for mips. When I changed to Big endian mode,
the following information appared, and the program hang.
-------------------------------------
Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
PDC20262: IDE controller on PCI bus 00 dev 30
PDC20262: chipset revision 1
PDC20262: not 100% native mode: will probe irqs later
PDC20262: ROM enabled at 0x06fb0000
PDC20262: (U)DMA Burst Bit DISABLED Primary PCI Mode Secondary PCI Mode.
ide0: BM-DMA at 0xf800-0xf807, BIOS settings: hda:pio, hdb:pio
ide1: BM-DMA at 0xf808-0xf80f, BIOS settings: hdc:pio, hdd:pio
hda: QUANTUM FIREBALL EX10.2A, ATA DISK drive
ide0 at 0xec00-0xec07,0xe802 on irq 7
hda: 20044080 sectors (10263 MB) w/418KiB Cache, CHS=19885/16/63, (U)DMA
Partition check:
hda:hda: dma_timer_expiry: status=0x58 { DriveReady SeekComplete
DataRequest }
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
-------------------------------------
When I turned off "IDE,ATA and ATAPI Block Devices->Generic PCI bus-master
DMA support", there was no problem at all. The following information
appared:

What could be the cause of this problem?
