PCI problems using DVB and older SCSI U160

I've got unexpected massive problems using DVB and older SCSI U160 adaptec asc-19160 host adapter on the nforce4 CK804 controlled PCI bus under 64Bit Linux+Windows which do not occur on VIA's KT890:
Green Flashes and massive disruption of other data streams on the bus if scsi hdd is (especially write) accessed. I've tried all the usual Stuff: acpi off, ioapic off, manual irq routing, swapping cards, latency timers, but cant get this problem solved. is this a chipset h/w bug? mainboard design can't be involved here.

adaptec is contacted for possibly adapter bios update, too.

ideas?

Other than updating to the latest BIOS for the motherboard, this sounds like a hardware problem.

Thanks,

thx.

maybe adaptec can do adapt the bus master through adapter bios or I can take a look on the aic7xxx driver.

otherwise , wrong forum from the beginning pls move thread to the hardware forum, thx.
