What kind of io chipset does your motherboard have? as there are a couple that have bugs under linux. That may be something to look at.
sorry not io, I meant ide.
Well most I/O functions tend to be integrated into the same chip and the IDE interface will be one component of that.
Still I guess what we really need to know is what chipset the IDE interface appears to be from a software point of view, so we are looking for lines from the output of dmesg like the following:
Uniform Multi-Platform E-IDE driver Revision: 6.31 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx AMD7409: IDE controller on PCI bus 00 dev 39 AMD7409: chipset revision 3 AMD7409: not 100% native mode: will probe irqs later AMD7409: disabling single-word DMA support (revision < C4) ide0: BM-DMA at 0xf000-0xf007, BIOS settings: hda:DMA, hdb:DMA ide1: BM-DMA at 0xf008-0xf00f, BIOS settings: hdc:DMA, hdd:DMA
But obviously with the AMD7409 replaced with whatever your chipset is. IIRC the CMD640 and the RZ1000 chipsets had bugs that required a specific work around to be enabled in the kernel's IDE driver but there may be others too.
