I can't do much about it ... Well known example are some via chipsets which have trouble with multiple devices doing DMA at the same time (those tend to run stable with bttv once you've turned off ide-dma ...). Getting broken hardware run stable and fast is black magic. You can try these (if that happens to help we can put that info into the pci quirks btw.): eskarina kraxel ~# modinfo bttv | grep "pci config" parm: vsfx:set VSFX pci config bit [yet another chipset flaw workaround] parm: triton1:set ETBF pci config bit [enable bug compatibility for triton1 + others] Otherwise BIOS updates, obscure BIOS settings, shuffling cards in PCI slots, enable/disable ACPI and/or APIC, whatelse may or may not help.
