Has anyone here successfully used a PCI IDE card on BCM91x80?
I immediately get lots of PCI DMA problems, e.g:


SiI680: IDE controller at PCI slot 0000:00:01.0
SiI680: chipset revision 2
SiI680: BASE CLOCK == 133
SiI680: 100% native mode on irq 8
    ide0: MMIO-DMA , BIOS settings: hda:pio, hdb:pio
    ide1: MMIO-DMA , BIOS settings: hdc:pio, hdd:pio
hda: FUJITSU MPB3043ATU E, ATA DISK drive
isa bounce pool size: 16 pages
ide0 at 0x9000000031080080-0x9000000031080087,0x900000003108008a on irq 8
hda: max request size: 64KiB
hda: 8448300 sectors (4325 MB), CHS=8940/15/63, UDMA(33)
 hda:<4>hda: dma_timer_expiry: dma status == 0x22
hda: DMA timeout error
hda: dma timeout error: status=0x01 { Error }
hda: dma timeout error: error=0x7f { DriveStatusError UncorrectableError 
SectorIdNotFound TrackZeroNotFound AddrMarkNotFound }, LBAsect=260013951, 
sector=0
ide: failed opcode was: unknown
end_request: I/O error, dev hda, sector 0
