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?

Update kernel.
My SIS chipset works like a charm with the latest kernel. First upgrade of kernel fixed all problems.
