Hi Mark,
try passing to the kernel during boot
ide=nodma
(may be ide1=nodma or ide2=nodma see if this is valid)
These are paramters to the installation program (that doesn't work during installation) but they may function to the kernel (who knows? this may be your luck day. Okay, this is just a try, forget abou it if it doesn't work)

I'm having difficulties keeping a server running under FC1 with a SiS5515 chipset and 2.4.22-1.2115.nptl kerenl from FC1 distro CDs. The main problem is with my secondary drive giving me errors like:
hdb: dma_timer_expiry: dma status == 0x41 dma_timer_expiry: dma status == 0x40 hdb: timeout waiting for DMA hdb: timeout waiting for DMA hdb: (__ide_dma_test_irq) called while not waiting hda: lost interrupt last message repeated 6 times hdb: irq timeout: status=0xd0 { Busy } ide0: reset: success
Which then under peak usage just hangs the server and eventually only a hard boot will bring it around.
I've already had to replace one HD for I/O bad sector errors, and now I can't seem to keep this HD going either. I'm trying to run with DMA off but it keeps getting reset by the kernel. This seems like a software problem as in FC and the chipset and IDE controller.

The sis5513 driver deliberatly overrides the CONFIG_IDEDMA_AUTO and the BIOS settings that might disable UDMA and forces UDMA which works for a while then fails, attempts to fallback to a non-DMA mode and fails that as well.
From my dmseg file:
Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4 ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx SIS5513: IDE controller at PCI slot 00:02.5 SIS5513: chipset revision 0 SIS5513: not 100% native mode: will probe irqs later SIS5513: SiS 962/963 MuTIOL IDE UDMA133 controller ide0: BM-DMA at 0xff00-0xff07, BIOS settings: hda:DMA, hdb:DMA
Any ideas?
